The RIM251K6-20 is a 1.6kW gallium-nitride (GaN) solid-state power amplifier (SSPA) designed for high-power industrial, scientific, and medical applications. (Microwave irradiation, sterilization, microwave sintering, microwave cladding, microwave joining, powder metallurgy). The RIM251K-6-20 is operable from 2400 to 2500 MHz and is designed with RFHIC’s state-of-the-art gallium-nitride (GaN) on SiC HEMTs providing excellent thermal stability and breakdown voltage. The RIM251K-6-20 is operable for both continuous wave (CW) and pulse applications. The RIM251K6-20 is equipped with RFHIC’s software suite allowing users to digitally control and monitor the amplifier’s power, frequency, and signal source. The RIM251K-6-20 is also equipped with high-grade isolators protecting the device up to 6:1 VSWR at max output power. In case a higher reflected power is detected, the amplifier will automatically shut down preventing amplifier failure.
