SA1921 - Satellite and cellular dual-band RF front-end

General Description

The SA1921 is an integrated dual-band RF front-end that operates at both cellular (AMPS, DAMPS, and GSM) and satellite (1515 1600 MHz) frequencies, and is designed in a 13 GHz fT BiCMOS process

QUBiC1.

The low-band is a combined low-noise amplifier (LNA) and mixer.

Key Features

  • Low current consumption.
  • Outstanding low- and high-band noise figure.
  • Excellent gain stability versus temperature and supply.
  • Image reject high-band mixer with over 30 dB of rejection.
  • Increased low-band LNA gain compression during analog.
  • LO input and output buffers.
  • On chip logic for network selection and power down.
  • Very small outline package.

INTEGRATED CIRCUITS SA1921 Satellite and cellular dual-band RF front-end Product specification Supersedes data of 1998 Sep 11 IC17 Data Handbook 1999 Mar 02 Philips Semiconductors Philips Semiconductors Product specification Satellite and cellular dual-band RF front-end SA1921 DESCRIPTION The SA1921 is an integrated dual-band RF front-end that operates at both cellular (AMPS, DAMPS, and GSM) and satellite (1515–1600 MHz) frequencies, and is designed in a 13 GHz fT BiCMOS process—QUBiC1. The low-band is a combined low-noise amplifier (LNA) and mixer. The LNA has a 1.7 dB noise figure at 943 MHz with 18.3 dB of gain and an IIP3 of –5 dBm. The wide-dynamic range mixer has a 11 dB noise figure at 943 MHz with 7.2 dB of gain and an IIP3 of +5 dBm.
