Abstract: Solid-state power amplifier modules have been widely adopted in navigation, radar, and jamming domains, whose performance directly determines the overall specifications of the entire system. This paper presents the design of an L-band continuous-wave 400W solid-state power amplifier module, with key focusing on addressing critical design challenges: broadband high-efficiency circuit topology, high-efficiency heat dissipation design, and low-loss high-power combining design for L-band modules. The experimental results verify that the developed module fully satisfies the system requirements, which can provide valuable theoretical guidance for the development of high-power L-band solid-state power amplifier modules.
