CML - Radio Frequency
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.
With an operating frequency ranging down to 20MHz and up to 1GHz, the RF products offer: a combination RF transceiver, a separate RF modulator, demodulator and a Cartesian feedback loop transmitter for efficiency and transmitter PA linearisation. CML's RF devices are designed for use in a wide range of both narrowband and wideband applications, in the wireless data and digital PMR markets.
