The LX5516 is a power amplifier

module

optimized

for

WLAN

applications

in

the

2.4-2.5GHz

frequency

range.

The

PAM

is

implemented as a two-stage monolithic

microwave integrated circuit (MMIC)

with on-chip active bias and 50

impedance matched at both input and

output.

The device is manufactured with an

InGaP/GaAs

Heterojunction

Bipolar

Transistor

(HBT)

IC

process

(MOCVD). With single low voltage

supply of 3.3V, it delivers 29dB power

gain between 2.4-2.5GHz, at a low

quiescent current of 80mA.

For 18dBm OFDM output power

(64QAM, 54Mbps), the PAM provides a

low EVM (Error-Vector Magnitude) of

2.5%, and consumes 130mA total DC

current.

The LX5516 is available in a 12-pin

2x2mm micro-lead package (MLPQ-

12L). The compact footprint, ultra low

profile, and thermal capability of the

MLP package make the LX5516 an

ideal

solution

for

high-gain

power

amplifier

requirements

for

IEEE

802.11b/g/n applications.
