Product Description

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 component count and eliminating the

need for IF SAW and RF interstage filters without com-

promising performance. The IC includes: four LNA’s for

multi-band support; an integrated voltage controlled oscil-

lator (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 POLARIS

solution.
