AGILTRON AMFPD User guide

  • Hello! I've reviewed the user guide for the AMFPD photodetector. This document describes how to set up and use the device, which features a switchable gain and a wide operating wavelength from 900 to 1700 nm. I'm ready to answer your questions about it.
  • What is the operating wavelength range of the AMFPD?
    What type of connector is used for the input signal?
    How is the gain adjusted?

Chapter 1 Descripon
The AMFPD is an amplied, switchable-gain, InGaAs photodetector in an FC/APC
Connector with an operang wavelength range of 900 to 1700 nm. Double
connector(J2) allows the user to vary the gain in 10 dB steps. A buered output
drives 50 Ω load impedances up to 5 V. The output signal is readable from the RF
SAM connector.
Chapter 2 Setup
2.1 input connector
See Fig 1, Input opc signal is connected with FC/APC connector.

2.2 power supply
The power supply is double DC 12V. To connect J1(2.54mm 3 pin connector), see
Fig 2.

Command power supply: Globtek GT-51084-12N12
2.3 output
Ouput is connected with RF SAM female adapter. A buered output drives 50 Ω load
up to 5V. See Fig 3

2.4 Gain (Av )Adjustment
The responsivity of a photodiode can be dened as a rao of generated
photocurrent (IPD) to the incident light power (P) at a given wavelength:
R(λ) = Ipd / P
Gain (Av )Adjustment:
Av= Ipd x Rf
Terminal J2 shut connector posion compaered with Gain:
Rf =100
Rf = 1000
Rf =10000
Rf =100000
