SA1921 Datasheet PDF (Satellite and cellular dual-band RF front-end)

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

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.

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.
