Low-Voltage, 400mA Step-Down DC-DC Converters in SOT23

General Description The MAX1920/MAX1921 step-down converters deliver over 400mA to outputs as low as 1.25V. These converters use a unique proprietary current-limited control scheme that achieves over 90 efficiency. These devices maintain extremely low quiescent supply current (50μA), and their hi

Dual-band RF front-end

DESCRIPTION The SA1920 is an integrated dual-band RF front-end that operates at both cellular (AMPS, GSM and TDMA) and PCS/DCS (TDMA and GSM) 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 noi
