The paper considers a block diagram, known constructions, and proposed design of a twofold reserved solid-state microwave power amplifier (RSSPA) for space-craft onboard equipment. Modern requirements of the RSSPA to a thermostatically controlled plate (TCP) used to remove heat from only one amplifier of the RSSPA are stated. The advantages and disadvantages of “two-storey” constructions and design with vertical positioning of power amplifier boards with respect to the TCP are shown. The paper p
