For +18dBm OFDM output power
(64QAM, 54Mbps), the PA provides a
very
low
EVM
(Error-Vector
Magnitude) of 4%, and consumes less
than 200mA total DC current.
The LX5503 is available in a 16-pin
3mmx3mm micro-lead package (MLP).
The compact footprint, low profile, and
excellent thermal capability of the MLP
package makes the LX5503 an ideal
solution for broadband, medium-gain
power amplifier requirements for IEEE
802.11a, and Hiperlan2 portable WLAN
applications.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
WWW . Microsemi .C OM
The LX5503 is a power amplifier
optimized for the FCC Unlicensed
National Information Infrastructure
(U-NII) band and HiperLAN2
applications in the 5.15-5.85GHz
frequency range. The PA is implemented as a two-stage monolithic
microwave integrated circuit (MMIC)
with active bias and input/output prematching. The device is manufactured
with an InGaP/GaAs Heterojunction
Bipolar Transistor (HBT) IC process
(MOCVD). It operates at a single low
voltage supply of 3.3V with +25dBm
of P1dB and 22dB power gain
between 5.15-5.35GHz and 18dB gain
up to 5.85GHz.

Bias current control voltage for the first stage.
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(R1/R2).
Supply voltage for the bias reference and control circuits. The VCC feed line should be
terminated with a 1 µF bypass capacitor as close to the device as possible. This pin can be
combined with both VC1 and VC2 pins, resulting in a single supply voltage (referred to as Vc).
RF output for the power amplifier. This pin is AC-coupled and does not require a DC-blocking
capacitor.
Power supply for first stage amplifier. The VC1 feedline should be terminated with a 220pF
bypass capacitor as close to the device as possible, followed by a 1µF bypass capacitor at the
supply side. This pin can be combined with VC2 and VCC pins, resulting in a single supply
voltage (referred to as Vc).
Power supply for second stage amplifier. The VC2 feedline should be terminated with a 220pF
bypass capacitor as close to the device as possible, followed by a 1 µF bypass capacitor at the
supply side. This pin can be combined with VC1 and VCC pins, resulting in a single supply
voltage (referred to as Vc).
The center metal base of the MLP package provides both DC and RF ground as well as heat
sink for the power amplifier.
