C-band RF power modules for radar applications

Communications Power & Industries (CPI) developed the VSC3645, C-Band gallium nitride (GaN) 4.2 kilowatt (kW) pursed solid-state radio frequency (RF) amplifier module to be combined to create high-power C-band radar transmitters for use in maritime surveillance and weather radar transmitters. The module covers the 5.2 – 5.9 GHz frequency band. The air-cooled GaN transistors with a combined 4.2 kW output – are air-cooled. The modules can be power-combined using waveguide combiners to achieve the higher power levels required for various radars.

Features include a building block for C-band radar systems, four combined 1.1 kW pulsed modules, high-efficiency GaN transistors; built-in-test (BIT) and controls via EIA-422 remote connection, blind mate DC and control connectors, and controllable output power reduction. Operating ambient temperature ranges between +5 +50 °C.
