PRODUCTION DATA SHEET
DESCRIPTION
LX5540 is a co-package RFIC For 20dBm OFDM output power
consisting of an InGaP/GaAs (64QAM, 54Mbps), the PA provides a
Heterojunction Bipolar Transistor low EVM (Error-Vector Magnitude) of
(HBT) power amplifier and a InGaAs 3%, and consumes 145 mA total DC
Enhancement mode pseudomorphic current.
HEMT (E-pHEMT) low noise The LNA offers 14 dB gain, 1.5 dB
amplifier. Both are optimized for noise figure and a high input IP3 of +4
WLAN applications in the 2.3-2.5 dBm at 10 mA of DC current.
GHz frequency range. The PA is LX5540 is available in a 16-pin
implemented as a two-stage 3mmx3mm micro-lead package
monolithic microwave integrated (MLPQ-16L). The compact footprint,
circuit (MMIC) with active bias and low profile, and thermal capability of
output pre-matching. The LNA is fully the MLP package makes the LX5540 an
matched internally and no external ideal solution for medium-gain power
matching circuit is required.
transmitter and very low noise receiver
Both devices operate with single requirements for IEEE 802.11b/g
low voltage supply of 3.3V. The PA applications.
offers 28 dB power gain between 2.3-
2.5GHz, at a low quiescent current of
80mA.
