Co-Package 2.3 – 2.5 GHz HBT Power
Amplifier & pHEMT Low Noise Amplifier
P RODUCTION D ATA S HEET
KEY FEATURES
DESCRIPTION
For 20dBm OFDM output power
(64QAM, 54Mbps), the PA provides a
low EVM (Error-Vector Magnitude) of
3%, and consumes 145 mA total DC
current.
The LNA offers 14 dB gain, 1.5 dB
noise figure and a high input IP3 of +4
dBm at 10 mA of DC current.
LX5540 is available in a 16-pin
3mmx3mm
micro-lead
package
(MLPQ-16L). The compact footprint,
low profile, and thermal capability of
the MLP package makes the LX5540 an
ideal solution for medium-gain power
transmitter and very low noise receiver
requirements for IEEE 802.11b/g
applications.

LX5540 is a co-package RFIC
consisting
of
an
InGaP/GaAs
Heterojunction Bipolar Transistor
(HBT) power amplifier and a InGaAs
Enhancement mode pseudomorphic
HEMT (E-pHEMT) low noise
amplifier. Both are optimized for
WLAN applications in the 2.3-2.5
GHz frequency range. The PA is
implemented
as
a
two-stage
monolithic microwave integrated
circuit (MMIC) with active bias and
output pre-matching. The LNA is fully
matched internally and no external
matching circuit is required.
Both devices operate with single
low voltage supply of 3.3V. The PA
offers 28 dB power gain between 2.32.5GHz, at a low quiescent current of
80mA.
