C-Band RF Power Modules
High efficiency, high power and compact with
proven GaN technology, the VSC3645 can be
easily combined to create high power C-band radar
transmitters.
CPI BMD’s solid state power amplifiers are reliable,
highly-efficient and easy to maintain. The VSC3645
solid state power amplifiers are designed for use in
maritime surveillance and weather radar transmitters and cover the 5.2 – 5.9 GHz frequency band.
GaN transistors are combined into a 4.2 kW output
and are air cooled. These modules can be power-combined using waveguide combiners to
achieve the higher power levels required for various
radars.
