RFHIC’s RIK2520K-40TG is a 20kW, GaN solid state microwave generator designed for industrial microwave drying, heating, and plasma generating applications. The RIK2520K-40TG is an integrated type microwave generator equipped with eight solid state power amplifier (SSPA) shelves, a 400 VAC power supply unit (PSU), a main control unit (MCU), and a WR430 waveguide output port. The RIK2520K-40TG is designed to replace conventional vacuum tubes (magnetrons, klystrons) with its longer lifetime and digital control features. The RIK2520K-40TG is equipped with a phase-lock-loop (PLL) synthesizer generating the desired signal in a precise and controllable manner. The RIK2520K-40TG is embedded with RFHIC’s precise control software suite allowing users to control and monitor the system’s power, RF mode (CW/pulse), and phase all digitally.  To protect the device from reflected power, the RIK2520K-40TG is pre-equipped with high-grade isolators (circulators, terms) preventing system failure. In case a higher reflected power is monitored the system will automatically shut down. The RIK2520K-40TG is water-cooled and has a dimension of 600 x 1800 x 750 mm.
