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. The LNA has a 1.7 d
