European EMC Directive

In order to meet the European Electro-Magnetic Compatibility (EMC) Directive (EN55022,

EN50082-1), properly shielded cables for DATA I/O are required. More specifically, these cables

must be shielded from end-to-end, ensuring a continuous ground shield.

The following information is applicable for the European Low Voltage Directive (EN60950):

<HAR> Type of power cord required for use in the European Community.

NOTES:

Chapter 1. Introduction

1.1 Overview

The Ku-Band Solid-State High Power Amplifier (KPA) is designed for use in

communication systems, or in satellite up-link data systems. The KPA (Figure 1-1)

operates over the RF input frequency range of 14.0 to 14.5 GHZ.

1.2 Functional Description

The KPA is designed to be hard mounted in a standard 19-inch (48 cm) rack or cabinet,

or to be rack mounted using Comtech EF Data slide mechanisms provided with the SSPA

to allow it to be serviced without its removal from the rack. Two internally mounted

exhaust fans are mounted on the chassis for cooling. An AC power connector, with an

On/Off switch, is located on the rear on the chassis. A six-foot AC power cord is supplied

with the unit.

All operator controls, indicators, and displays for local and remote operation as well as

the RF Input and Output sample test ports are located on the front panel of the unit.

Connectors for the external interface connections are located on the rear of the unit

chassis.

The KPA (Figures 1-2, 1-3, or 1-4) consists of a chassis, power supply, fan assembly,

front panel assembly, monitor/control processor (MCP) and a Comtech EF Data solid-

state power amplifier (SSPA) module. The KPA is designed using a Comtech EF Data

low loss combining technique and an MCP based temperature versus gain compensation.

The front panel contains a user-friendly LCD menu display and cursor control key in

order to display status or change parameters. The front panel also has LEDs for quick

reference to binary status points and both input and output sample ports at –20 dBc and

–40 dBc for easy test point access.

Ku-Band Solid-State Power Amplifier Revision 0

Introduction MN/KPA.IOM

1-2

Each unit has the ability to function as a 1+1 or 1+2 redundancy controller in the backup

mode. The optional redundancy configuration is implemented by attaching a ganged

Waveguide/coax transfer switch (es) to input and output connectors of the amplifiers with

a combination coaxial cable and Waveguide kit.

When the backup KPA is commanded into the controller mode, it monitors the online

KPA’s for faults. A faulted online unit may be disconnected and replaced without

affecting the online power amplifier.

2.1 Unpacking

Perform a receiving inspection as follows:

• Inspect the shipping container for damage. The shipping container and packing

materials should be retained for possible reshipment.

• Check to determine that all parts, materials and documentation have been shipped

with the KPA. The KPA should be inspected for possible damage, and then tested for

proper operation.

• If the shipment exhibits any of the following, contact Comtech EF Data Customer

Support:

♦ Incomplete

♦ Mechanical damage

♦ Inoperable

If there is damage to the shipping container, notify the carrier. Retain all shipping

materials for inspection by the carrier.
