What CML Microcircuits does

CML Microcircuits (UK) Ltd, a subsidiary of CML Micro plc, is a fabless semiconductor company headquartered in Maldon, Essex, England, that designs and supplies mixed-signal, RF, and microwave semiconductors for global communications markets. The company's product portfolio is organized into eight product families: RF Building Blocks (transceivers, PAs, synthesizers, quadrature modulators), Digital/Analogue Two-Way Radio (PMR/LMR baseband processors supporting DMR, dPMR, TETRA), Maritime Communications (AIS processors, VDES modules), Wireless Data (multi-mode modems for IoT, SCADA, RTK), Digital Voice (RALCWI/CVSD vocoders), Broadcast (DRM receiver modules and SDR tuners), Wireline Telecom (legacy modem ICs), and SµRF RFICs/MMICs spanning DC to 50 GHz. Underlying technology rests on the proprietary FirmASIC reconfigurable IC platform, the exactTrax AIS embedded technology, and the SµRF GaN/III-V product line, supported by comprehensive evaluation kits and reference designs. Featured recent products include the CMX918 ultra-low-power SDR tuner (5x5 mm, 150 kHz-108 MHz) and the CMX90A705 5.5W Ka-Band GaN power amplifier.

The company serves OEMs and system integrators across six primary verticals: Critical Communications, Wireless Networks & Satellite, Aerospace & Defence, Broadcast, IoT/M2M, and Maritime Communications. It operates a sales-led, B2B go-to-market selling exclusively through a global distributor network, with revenue generated from hardware sales of semiconductor components under quote-based pricing. Geographic focus is global, with active market-development efforts in India (DRM digital radio) and Indonesia (DRM/DAB+ dual-standard), and visibility at industry events such as IMS 2026. The company holds Cyber Essentials certification and its leadership participates in industry standards bodies, including as Vice-Chair of the DRM Consortium. Production is outsourced to foundries, with CML operating as a design-intensive intellectual property hub.
