LX5541 Overview
LX5541 is a co-package RFIC consisting of an InGaP/GaAs Heterojunction Bipolar Transistor ..net (HBT) power amplifier, an InGaAs pseudomorphic HEMT (pHEMT) low noise amplifier, and a SPDT switch. All three RF devices are optimized for WLAN applications in the 2.3 to 2.5 GHz frequency range. The PA is implemented as a twostage monolithic microwave integrated circuit (MMIC) with active bias and output pre-matching.
