RF2722 Datasheet | RF Micro Devices

Description -A- 2 PLCS 0.10 C A 0.05 C 0.90 0.85 The RF2722 is a highly-integrated receiver IC supporting GSM, GPRS, and EDGE cellular standards in the GSM850, EGSM, DCS, and PCS bands. The RF2722 supports both very-low intermediate frequency (VLIF) as well as direct conversion receive (DCR) architectures, reducing external ponent count and eliminating the need for IF SAW and RF interstage filters without promising performance. The IC includes: four LNA’s for multi-band support; an integrated voltage controlled oscillator (VCO); automatic gain control (AGC); a quadrature downconverting mixer; and, low and high band transmit buffers. Chip functionality, including IF AGC setting, is controlled through a three-wire serial data interface (SDI). The RF2722 is part of the POLARISTM TOTAL RADIOTM solution.
