RF Building Blocks

CML’s range of Radio Frequency (RF) products provides a selection of modular building blocks for implementation as part or all of the ‘wireless front-end’ of a wide range of constant and non-constant envelope modulation systems. The new RF Building Block range is designed to provide flexible, high-performance ICs required for HF/VHF/UHF professional radios, wireless data terminals, wireless microphones and marine and avionics radio systems.
