INTEGRATED CIRCUITS SA1620 Low voltage GSM front-end transceiver Product specification Supersedes data of 1996 Oct 08 IC17 Data Handbook 1997 May 22 Philips Semiconductors Philips Semiconductors Product specification Low voltage GSM front-end transceiver SA1620 DESCRIPTION The SA1620 is a combined receive (Rx) and transmit (Tx) front-end for GSM cellular telephones. The receive path contains two low noise amplifiers (LNA1 and LNA2) with four switchable attenuation steps. A Gilbert Cell mixer in the receive path down-converts the RF signal to a first IF of 70 to 500 MHz. A second Gilbert Cell in the transmit path transposes a GMSK or phase modulated IF to RF by image reject mixing and has a fixed IF of 400 MHz. A buffered LO signal is fed to Rx and Tx mixers.
