功能特点

RDA5206A PHS transceiver

The RDA5206A transceiver is a complete RF front end for PHS wireless communication. The receive section interfaces between the RF band-select filter and the baseband subsystem. The RDA5206A receiver employs a digital low-IF architecture, and universally supports analog baseband interfaces. The transmit section of RDA5206A provides a direct up-conversion path from the baseband subsystem to the power amplifier (PA). A fast settling fractional-N synthesizer is fully integrated, including RF VCO, loop filters, and varactors, etc. The RDA5206A transceiver includes a digitally-controlled crystal (DCXO) and completely integrates the reference oscillator and varactor functionality.
