Company profile
Forefront RF
Fabless company developing RF front-end filtering chips for multi-band mobile devices.
Company overview
Forefront RF is a fabless semiconductor company based in Cambridge. It develops reconfigurable radio frequency (RF) front-end solutions for mobile and Internet of Things (IoT) devices. The company's core technology, Foretune™, is a tunable duplexer designed to address the growing complexity and cost associated with supporting numerous frequency bands in 4G and 5G networks. This technology replaces the traditional approach of using banks of fixed hardware, such as filters and switches, with a single, adaptive chip. By doing so, it aims to simplify the RF front-end architecture, reduce component count, and lower power consumption. This enables device manufacturers to streamline their supply chains and reduce the need for multiple regional product variants. The solution supports RF bands in the low-band category.
