PRODUCTION DATA SHEET
DESCRIPTION
LX5541 is a co-package RFIC For 19dBm OFDM output power
consisting of an InGaP/GaAs (64QAM, 54Mbps) at the antenna port,
Heterojunction Bipolar Transistor the PA including SPDT switch provides
www.(DHatBaSThe)et4pUo.wneet r amplifier, an InGaAs a low EVM (Error-Vector Magnitude)
pseudomorphic HEMT (pHEMT) low of about 3%, and consumes 145 mA
noise amplifier, and a SPDT switch. total DC current.
All three RF devices are optimized for The LNA (including SPDT switch
WLAN applications in the 2.3 to 2.5 loss) offers 13 dB gain, 2 dB noise
GHz frequency range.

The PA is implemented as a two- and a high input IP3 of +5 dBm at 10
stage monolithic microwave integrated mA DC current.
circuit (MMIC) with active bias and LX5541 is available in a low profile
output pre-matching. The LNA is fully 16-pin 3mmx3mm micro-lead package
matched internally, and the LNA is (MLPQ-16L). LX5541 with a PA,
connected to the RX port of SPDT LNA and SPDT integrated in a small,

The PA (including SPDT switch loss)
offers 27 dB power gain between 2.3-
2.5GHz, at a low quiescent current of
90mA.
