4.3.6 High Power RF Power Amplifier Module (HPA)
The RF High Power Amplifier (HPA) assembly EA-555014 (shown in Figure 4-10), amplifies the exciter
output to the rated station output power level. This module contains a power module, amplifier drivers,
and power control circuitry required for power amplification.
The Power Amplifier assembly is a continuous duty, solid state, wide-band RF power amplifier. Its main
function is to amplify the 0 dBm signal from the TX module to the rated RF output at the antenna port.
The RF output of the Power Amplifier Assembly is capable of up to 100 Watts (adjustable from 10 to
100 Watts) as measured at the PA output port.
