At IMS 2026, everything RF conversed with Grace Cho, Head of Global Sales and Marketing, RFHIC. At their booth #24054, Cho highlighted the company’s expanding portfolio of GaN-based solutions across radar, telecommunications, RF energy, and defense applications.
RRK273118K-690RFHIC’s solid-state transmitter systems are designed for radar platforms, positioned as replacements for traditional tube-based systems. The company offers turnkey transmitter solutions covering L-band to X-band frequencies, supporting maritime and ground-based radar applications. One of the key systems demonstrated was RRK273118K-690, an 18 kW S-band transmitter, integrating redundant solid-state power amplifiers (SSPAs), driver amplifiers, control modules, and hot-swappable SSPAs and power supplies. These modular features are designed to improve system reliability, simplify maintenance, and support continuous operation in mission-critical environments.
The presentation also highlights RFHIC’s telecommunications portfolio, including GaN hybrid amplifiers and GaN transistor solutions targeting sub-6 GHz 5G infrastructure. These solutions are offered as integrated evaluation board platforms, combining amplifiers and transistors into a unified form factor to enable faster testing and development. The approach is aimed at reducing design complexity while accelerating time to deployment for wireless infrastructure applications.
For high-frequency and advanced communications, RFHIC showcased its GaN MMIC portfolio, supporting applications in defense, satellite, and space systems. These solutions extend into X-band and Ka-band frequency ranges, addressing the demand for compact, high-efficiency components in next-generation communication and sensing systems.
RCM251K6-20GOn the RF energy side, Cho presented high-power continuous-wave (CW) solid-state solutions for industrial, scientific, and medical applications. These systems are designed for use cases such as linear accelerators and semiconductor processing, where high efficiency, compact form factors, and stable power delivery are critical. A key highlight was the RCM251K6-20G, a GaN Solid-State Microwave Generator that operates from 2400 to 2500 MHz. It is designed to replace conventional magnetrons and is ideal for microwave heating and plasma generation applications. The RCM251K6-20G integrates a PLL synthesizer with an internal reference, eliminating the need for an external signal source.
RRM9397800-59A, RFHIC’s defense portfolio was another focus area in the booth demonstration. Cho outlined a range of solutions including GaN-based transmit/receive modules and hybrid amplifiers for electronic warfare (EW), jamming, and seeker applications. These solutions cover S-band to X-band frequencies, supporting various defense system requirements. She also talked about their pulse amplifier systems for radar applications, including narrowband solutions across L to X bands. A highlighted example was RRM9397800-59A, an 800 W amplifier operating in the 9.3–9.7 GHz range, designed for radar performance and signal precision.
In addition, RFHIC presented its wideband amplifier platforms, covering a broad frequency range from 20 MHz to 6 GHz. These solutions are designed for multi-purpose applications such as EW systems, tactical communications, and counter-drone technologies, where wideband coverage and flexibility are essential.
