The report describes the design and characteristics of an ultra-wideband solid-state microwave power amplifier based on modern monolithic integrated circuits, providing output power of more than 12 - 16 W and efficiency of 14 to 20% in the operating frequency range from 5 to 18 GHz. 

Due to growing needs to reduce weight and size characteristics, reduce power consumption of broadband radio transmitting devices, the developers of microwave modules tend to use modern integrated components based on gallium nitride technology in the output stages of power amplifiers [1]. This solution greatly simplifies the amplifier design in comparison with solutions based on discrete GaAs transistors [2] while improving the basic parameters of the amplifier.
