4.0 Introduction
This section contains information on the theory of operation of the Compact Outdoor Solid
State Power Amplifier. This includes a discussion of the system block diagram, amplifier
module operation, and unique cooling system.
The Compact Outdoor Solid State Amplifier has been designed to be an extremely robust
microwave amplifier system. It 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.
Proprietary thermal management techniques allow even the highest output power level
amplifiers 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:
