Chapter 1. Introduction
1.1 Overview
The K u-Band Solid-State High P ower A mplifier (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.
