Forefront RF is a fabless semiconductor company developing breakthrough tunable duplexer technology (Foretune™) that simplifies mobile radio front-end designs in smartphones, wearables and IoT devices. Their patented adaptive passive cancellation technology replaces multiple fixed frequency components with a single dynamically tunable module, dramatically reducing PCB space while supporting more frequency bands. Founded by Cambridge University research, the company completed its £16 million Series A in November 2024 and is preparing to launch its first commercial products for the cellular-enabled smartwatch market in 2026. The technology addresses a major bottleneck in RF design and has attracted interest from several smartphone and smartwatch manufacturers.
