APPLICATIONS
The LX5510 is a power amplifier
optimized for WLAN applications in
the 2.4-2.5GHz 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 20dB power gain
between 2.4-2.5GHz, at a low
quiescent current of 65mA.
For +19dBm OFDM output power
(64QAM, 54Mbps), the PA provides a
low EVM (Error-Vector Magnitude) of
3.0%, and consumes 120mA total DC
current with the nominal 3.3V bias.
With increased bias of 4.5V EVM is ~
5% at 23dBm.
The LX5510 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 LX5510 an ideal
solution for medium-gain power
amplifier requirements for IEEE
802.11b/g applications
