Overview

Phase combining is a traditional technique that cost effectively increases the available output
power of an amplifier system. The PCB-4000A 1+1 Phase Combiner (Figure 1-1), together with
two Solid State Power Amplifiers (SSPAs), form a complete 1+1 phase combined system that
doubles the available output power. The PCB-4000A also features a "soft fail" configuration; i.e., if
one SSPA experiences a failure, the total output power will be reduced by only 3 dB, rather than
6 dB.
