InGaP HBT 2.4 â 2.5 GHz Power Amplifier
PRODUCTION DATA SHEET
DESCRIPTION
The LX5518 is a high gain and high LX5518 also features an on-chip
power amplifier optimized for power detector at the output port of
802.11b/g/n applications in the 2.4-2.5 the PA to help reduce BOM cost and
GHz frequency range. The PA is PCB space for implementation of
implemented as a three-stage monolithic power control in a typical wireless
microwave integrated circuit (MMIC) system.
with active bias, on-chip input The LX5518 is available in a 16-
matching, and output pre-matching.
pin 3mm x 3mm quad flat no lead
The device is manufactured with an package (QFN 3Ã3-16L). The
InGaP/GaAs Heterojunction Bipolar compact footprint, low profile, and
Transistor (HBT) IC process excellent thermal capability make the
(MOCVD). It operates with a single LX5518 an ideal solution for
positive voltage supply of 3-5V, and 802.11b/g/n applications.
provides a power gain of 30dB and an
output power of +26dBm at 5V for 3%
EVM in the 2.4-2.5GHz.
