1 Introduction
1.1 Overview
This document is the user’s guide for the TRF3711xxEVM. The TRF3711xx is a receiver direct
downconvert quadrature demodulator that includes programmable baseband filters, adjustable dc offset
correction, and buffer amplifiers to directly drive ADCs. The device is suited for operation with WCDMA,
WiMAX, and LTE modulation as well as with other high-bandwidth signal modulation schemes.
Note: Unless otherwise noted, the abbreviations TRF3711xxEVM and TRF3711xx are used in this
document to refer to all members of this device family (including the TRF371109, TRF371125, and
TRF371135). Table 1 summarizes the TRF3711xx device frequency options and lists the recommended
balun for each device.

There is considerable overlap in the operating frequency range of the TRF3711xx family of devices.
Refer to the specific device data sheet and compare performance parameters at the frequencies of
interest to select the best part for a particular application.
1.2 EVM Frequency Configuration Options
The TRF3711xx device is inherently broadband; however, the RF input and LO input require differential
input, which is generally achieved with the use of an RF balun. The EVM can be configured with a
different balun to facilitate operation in the desired band. Inspect the board at R101 to R105 to determine
which balun is populated on the board.
1.3 System Block Diagram
The basic radio system block diagram in Figure 1 demonstrates where the TRF3711xx fits in the overall
receiver architecture. The bold box highlights the TRF3711xx device.

3.1 Test Block Diagram
The test setup for general testing of the TRF3711xx is shown in Figure 3.
Figure 3. Test Setup Block Diagram
3.2 Test Equipment
The following equipment is required for completing RF testing:
● Power supply with current readout (Agilent E3631 or equivalent)
● Signal generator for input signal (Agilent E4438C or equivalent)
● Signal generator for LO signal (Agilent E4438C or equivalent)
● Spectrum analyzer (Agilent E4440A or equivalent)
● Programming computer
3.3 Calibration
The RF cables should be good-quality RF cables because of the high-frequency signals.
NOTE: There is approximately 1 dB of insertion loss for the input traces and balun on the printed
circuit board (PCB).
• Measure the insertion loss of the RF input cable and use this value to compensate for the desired input
power.
• Measure the insertion loss of the LO input cable and use this value to compensate for the desired LO
power.
• BB loss factor: If using the onboard transformers to interface with 50-Ω test equipment, then there is
approximately 12 dB of loss associated with the voltage transformation and transformer loss.
4 Basic Test Procedure
This section outlines the basic test procedure for testing the EVM. This section is divided into three test
sections: DC Test, Basic RF Test, and Advanced RF Test. The first section requires only power supply
with current readout and a computer for programmability. The second section requires basic RF test
equipment and basic technical know-how. The third section is for reference and requires specialized
equipment and setup. Only Section 4.1 and Section 4.2 are required to ensure basic functionality.
4.1 DC Test
1. Connect +5 V to J11; connect ground to J12.
2. Engage power supplies.
3. Verify current is 385 mA ± 25 mA.

Basic Test Procedure
www.ti.com
4.2 Basic RF Test
Determine which balun device is placed on the board by inspecting which jumper resistor is installed at the
R101 to R105 locations. This information determines the proper RF frequencies for which the board is
configured. Table 2 summarizes the frequency band allocations.
Table 2. Frequency Allocations
Band Frequency Band F_LO F_RF
1G9 1800 MHz to 2000 MHz 1.9 GHz 1.9 GHz
2G4 2.3 GHz to 2.7 GHz 2.4 GHz 2.4 GHz
3G5 3.5 GHZ to 3.8 GHz 3.5 GHz 3.5 GHz
1G7 1600 MHz to 1800 MHz 1.7 GHz 1.7 GHz
900M 700 MHz to 1000 MHz 900 MHz 900 MHz
1. Inject LO signal at J7 at F_LO frequency at 0 dBm. Compensate for RF cable losses, including about 1
dB for input balun and transmission line losses.
2. Verify USB cable is connected.
3. Launch TRF3711_GUI_vxpx.
4. Toggle Auto Cal En on the GUI to complete a dc offset calibration.
5. Monitor the dc voltage are TP2 (IA) and TP7 (IB) and between TP10 (QA) and TP12 (QB) and verify
that the dc offset voltage is 0 ±35 mV.
6. Inject RF signal at J6 at F_RF + 300 kHz at –40 dBm. Compensate for cable loss including about 1 dB
for input transmission line losses and balun.
7. Connect spectrum analyzer at J3 (I).
8. Set Spectrum analyzer center frequency to 300 kHz:
(a) Set span to 500 Hz.
(b) Set reference level to 0 dBm.
(c) Set analyzer to dc coupling.
(d) Set RBW to 3 Hz.
(e) Set VBW to 10 Hz.
9. Measure the signal at 300 kHz and verify signal at –12 dBm ±4 dB; note there is at least 12 dB of loss
associated through the onboard transformer. Also note that the device gain depends on the frequency,
and thus the output levels differ, depending on the frequency of the test.
10. Adjust BB gain to 20; verify signal reduces 4 dB ±1 dB.
11. Switch output cable to J10 (Q) and repeat the basic RF test beginning with Step 9..
4.3 Advanced RF Test
The EVM is equipped with the differential outputs going to a 16:1 transformer for interfacing with 50-Ω test
equipment. This configuration is suitable for completing basic RF test evaluation of the device; however,
the inherent high-pass nature of a transformer limits performance at frequencies close to dc. As a result,
this configuration is not suitable for analyzing true modulated signals. As an alternative, the ports at J2/J4
and J8/J13 offer direct access to the driver amplifier outputs for the differential I and Q signals,
respectively. Note, these ports cannot drive 50-Ω test equipment directly. For best performance, the
connections to the transformer should be severed by removing jumpers at W4, W5, W6, and W7.

Basic Test Procedure
These ports can drive into an ADC directly or into a high-impedance differential amplifier. These ports are
dc-coupled to provide the proper common-mode offset voltage to the ADC. The typical EVM performance
of the device using a modulated 3.5-MHz wide WiMAX signal captured by the ADC is shown in Figure 4.

Optional Configurations
www.ti.com
5 Optional Configurations
5.1 Mixer Outputs
The mixer outputs can be fed directly to the transformers and to ports J5 and J9. This can be useful for
measuring the RF performance of the mixer itself without the PGAs or filters. This feature is implemented
by toggling the BUF Pwd to Off.
5.2 Common-Mode Voltage
The common-mode voltage is set to a static 1.5 V by a resistor-divider network. Note, the common-mode
voltage is shifted if the input supply is not 5 V. Alternatively, this can be controlled via a potentiometer by:
• Removing R17, R18
• Placing 0-Ω jumper at R19
• Adjusting potentiometer R20.
When cascading the device with an ADC it may be desirable to feed the common-mode voltage from the
ADC to the device. This can be accomplished by:
• Removing shunt at W3
• Placing ADC common-mode voltage at TP9
5.3 DC Offset Control
The easiest way to manage the dc offset control is to use the Auto Cal function. This is accomplished by
setting Auto Cal to Auto and toggling the Auto Cal En switch. Monitor the dc offset voltage at TP2 (IA) and
TP7 (IB) and between TP10 (QA) and TP12 (QB) and verify that the procedure worked sufficiently.
The detection filter is typically set to 1 kHz and the clock divider is set to 1024. With this configuration the
dc offset calibration is most accurate and can be enabled with the RF signal present. If the RF input signal
is disabled during the auto-cal procedure, then the detection filter bandwidth can be 10 MHz and the clock
divider reduced to a value of 16. Other combinations of detector filter and clock divider are possible,
depending on accuracy required and convergence time required.
Alternatively, this function can be accomplished by manually programming the I and Q DAC registers.
Toggle Auto Cal to Manual. Adjust the I and Q DAC registers on the GUI directly. Monitor the dc offset
values at TP2 (IA) and TP7 (IB) and between TP10 (QA) and TP12 (QB) until the dc offset is as close to 0
mV as possible.
5.4 Analog Gain Control
The device is equipped with three bits to control the PGA gain to facilitate an analog gain-control loop that
does not require the use of SPI. To use this function, set the EN_FastGain to ON. Then adjust for the gain
through the binary combination of bits B0, B1, B2 that can be toggled at DIP switch SW1. For example, if
the BB gain is set to 24 and the binary bits are set to b101, then the equivalent gain setting is 24 – 5 = 19.
If the GainSelect is set to 2×, then the equivalent gain setting for the previous example is
24 – 2 × 5 = 14.
5.5 Analog Device Disable
The TRF3711xx can be disabled by removing the jumper at W2.

days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY
SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all
claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to
take any and all appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER
FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of
patents or services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the
product. This notice contains important safety information about temperatures and voltages. For additional information on TI’s
environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh.
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM Warnings and Restrictions
It is important to operate this EVM within the input voltage range of 4.5 V to 5.5 V and the output voltage range of 0 V to 4 V .
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 55° C. The EVM is designed to
operate properly with certain components above 55° C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
