Блок-схема заявляемого изобретения показана на Фиг. 1. The block diagram of the claimed invention is shown in Fig. one.
Принцип работы твердотельного усилителя мощности L-диапазона сводится к тому (см. блок-схему), что сверхвысокочастотный сигнал поступает на его вход и через плату ограничителя мощности (1) поступает к 1-му комбинированному каскаду усилителя (2) и далее через делитель мощности (3) на 2-й комбинированный каскад усилителя (4), потом после сумматора мощности (5) и на 3-й комбинированный каскад усилителя (6), в которых осуществляется усиление сверхвысокочастотного сигнала до необходимого уровня.
