GSM transceiver
RDA6210DM
The RDA6210 transceiver is a complete RF front end for GSM/GPRS wireless communication. The receive section interfaces between the RF band-select SAW filter and the baseband IC. The RDA6210 receiver employs a digital low-IF architecture, and universally supports analog baseband interfaces. The transmit section of RDA6210 provides a direct modulation PLL transmitter 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 RDA6210 transceiver includes a digitally-controlled crystal (DCXO) and completely integrates the reference oscillator and frequency tuning varactors.
