RFHIC’s RIM25100-20G is a 100W, GaN solid-state microwave generator designed ideally for microwave ablation (tumor, liver, cardiac, tissue) and microwave diathermy applications. The RIM25100-20G is built with RFHIC’s cutting-edge gallium-nitride (GaN) on SiC HEMTs, providing excellent thermal stability and efficiency. The RIM25100-20G is a modular type microwave generator equipped with a phase-lock-loop (PLL) synthesizer providing a stable and precise signal for the generator. The RIM25100-20G is also embedded with RFHIC’s precise software suite allowing users to sweep and adjust the frequency, power, RF mode, and phase. The RIM25100-20G has a dimension of 200 x 100 x 30 mm and weighs approximately 1.16kg. The RIM25100-20G does not require an external RF input, simplifying system integration and lowering costs.
