Advanced GaAs and GaN MMIC products enable next-generation Ku- and Ka-band satellite payloads, gateways and constellations

Maldon, Essex 4 March 26. CML Micro, a leading developer of mixed-signal, RF and microwave semiconductors for global communications markets, will be showcasing its latest high-performance mmWave and wideband RF capabilities at Space-Comm Expo, London ExCeL, 4–5 March 2026. The company can be found at Stand B4a.

As the aerospace and defence industries accelerate deployment of next-generation mmWave platforms, demand continues to grow for compact, power-efficient and high-reliability RF solutions, alongside increasing focus on resilient, regionally supported supply chains. CML Micro’s extensive portfolio of GaAs and GaN MMIC amplifiers and gain blocks is engineered to meet these evolving requirements across spaceborne platforms, wideband architectures and emerging inter-satellite systems.

CML Micro’s solutions cover the full satellite communications ecosystem, from HTS payloads and gateway infrastructure to compact gain stages supporting LEO, MEO and GEO constellations. Optimised for size, weight and power (SWaP) efficiency, the devices deliver the linearity and output performance needed for phased arrays, SatCom terminals and integrated space and ground systems. The portfolio is further bolstered by defined screening and qualification pathways, enabling designers preserve signal integrity in power- and space-constrained environments while meeting stringent reliability standards for mission-critical aerospace programmes.

Products on display include:

• MMA-005022B – 30kHz–50GHz Traveling Wave Amplifier
  A broadband GaAs MMIC amplifier delivering continuous coverage from 30kHz to 50GHz, providing consistent gain and wideband performance for satellite platforms, defence communications, and advanced test and monitoring applications.
• MMA-243034D-M5 – 24–30GHz, 2.5W MMIC Power Amplifier
  A high-efficiency Ka-band GaAs MMIC power amplifier delivering 2.5W across 24–30GHz, ideal for satellite uplinks, gateways and phased-array systems requiring compact, high-linearity performance.
• CMX90A705 – 5.5W Ka-Band GaN Power Amplifier
  A high-power-density GaN-on-SiC amplifier delivering 5.5W output in the Ka-band, designed for high-throughput satellite payloads and demanding RF environments.

“Satellite and aerospace programmes are gaining momentum, placing new demands on RF performance, efficiency and integration,” explains Malcolm Lomer, Regional Sales Manager EMEA at CML Micro. “At Space-Comm Expo, we will be demonstrating solutions that address today’s payload and ground system requirements while supporting the next wave of high-frequency, high-capacity satellite technologies.”

With more than 40 years of RF and mmWave expertise, CML Micro delivers engineering-led support, from initial concept through to design, qualification and production. The company combines deep systems knowledge with a comprehensive portfolio of gain blocks, drivers, and power amplifiers, offering compelling price-performance solutions backed by UK based design and test capabilities to help strengthen resilient supply chains. CML Micro’s portfolio is available through a global network of trusted distribution partners.

Visitors to Space-Comm Expo are invited to book a meeting with Malcolm Lomer, Regional Sales Manager EMEA, to explore how CML Micro’s RF and mmWave portfolio can be integrated into specific satellite and advanced aerospace programmes, either as part of an integrated solution or within broader platform architectures.
