KEY FEATURES
DESCRIPTION
For +19dBm OFDM output power
(64QAM, 54Mbps), the PA provides a
low EVM (Error-Vector Magnitude) of
3.0%, and consumes 125 mA total DC
current with the nominal 3.3V bias.
With increased bias of 5 V EVM is ~
4% at 23 dBm.
The LX5510 is available in a 16-pin
3mmx3mm micro-lead quad package
(MLPQ). The compact footprint, low
profile, and excellent thermal capability
of the MLPQ package makes the
LX5510 an ideal solution for mediumgain power amplifier requirements for
IEEE 802.11b/g applications

The LX5510 is a power amplifier
optimized for WLAN applications in
the 2.4-2.5 GHz frequency range. The
PA is implemented as a two-stage
monolithic microwave integrated
circuit (MMIC) with active bias and
input/output pre-matching.
The device is manufactured with an
InGaP/GaAs Heterojunction Bipolar
Transistor
(HBT)
IC
process
(MOCVD). With single low voltage
supply of 3.3V 20 dB power gain
between 2.4-2.5GHz, at a low
quiescent current of 65mA.

FUNCTIONAL PIN DESCRIPTION
Name
RF IN
Description
RF input. This pin is DC-shorted to GND but AC-coupled to the transistor base of the first stage.
VB1
Bias current control voltage for the first stage.
VB2
Bias current control voltage for the second stage. The VB2 pin can be connected with the first stage control
voltage (VB1) into a single reference voltage (referred to as Vref) through an external resistor bridge.
VCC
Supply voltage for the bias reference and control circuits. This pin can be combined with both VC1 and VC2 pins,
resulting in a single supply voltage (referred to as Vc).
RF OUT
RF output.
Power supply for first stage amplifier. The VC1 feedline should be terminated with a 3.3 pF bypass capacitor,
followed by a 8.2 nH blocking inductor at the supply side.
VC2
Power supply for second stage amplifier. The VC2 feedline should be driven with a 8.2 nH AC blocking inductor
and 1 uF bypass capacitor.
GND
The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the power
amplifier.
