KEY FEATURES
DESCRIPTION
LX5541 is a co-package RFIC consisting of an InGaP/GaAs Heterojunction Bipolar Transistor www.DataSheet4U.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. The LNA is fully matched internally, and the LNA is connected to the RX port of SPDT switch directly inside the MLPQ package. Both PA and LNA operate with single low voltage supply of 3.3V.
