Beschreibung
Zusammenfassung:	A Passive-Redundant UHF amplifier circuit which acts as its own fault sensor and automatically adjusts and compensates for individual amplifier degradation is described. It is essentially a parallel circuit, operating to maintain a constant output, whether one amplifier fails completely or both degrade gracefully. The circuit was designed for 435 MHz and tested for operation over the frequency range of 400 to 470 MHz. It is suitable for use in stages of a system where power transfer is not critical. (Author)
