Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV B 47
4.0 Introduction
This section of the manual describes the operation of the Compact Outdoor Solid State Power
Amplifier. The Compact Outdoor unit has been designed for maximum flexibility in amplifier
system configuration.
The Compact Outdoor Solid State Amplifier is very well suited for environmentally demanding
conditions where reliability is paramount. At the heart of the amplifier system is a multifunction
solid state power amplifier (SSPA) module. It has a full compliment of parallel I/O monitor
and control signals as well as serial I/O capability using a PC and host communication
software from Teledyne Paradise Datacom LLC.
Proprietary thermal management techniques allow even the highest output power level ampli-
fiers to operate reliably in environments up to 60°C ambient temperature and 100% relative
humidity.
Figure 4-1 shows the block diagram of the amplifier system. As seen in the block diagram
there are five major active components:
1. AC/DC Converter
2. DC/DC Converter
3. Solid State Power Amplifier Module
4. Fan Boost Converter
5. Cooling System
