The LX5503 is a power amplifier
optimized for the FCC Unlicensed
National Information Infrastructure
(U-NII)
band
and
applications in the 5.15-5.85GHz
frequency range. The PA is im-
plemented 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). 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.
HiperLAN2
For +18dBm OFDM output power
(64QAM, 54Mbps), the PA provides a
very
low
EVM
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.
