2.4 GHz High-Efficiency, High-Gain Power Amplifier Module - SST12LP14E

2.4 GHz High-Efficiency, High-Gain Power Amplifier Module
SST12LP14E
A Microchip Technology Company
Product Brief
SST12LP14E is a high-efficiency, ultra-compact power amplifier (PA) based on
the highly-reliable InGaP/GaAs HBT technology. Designed to operate over the 2.4
- 2.5 GHz frequency band, SST12LP14E typically provides 23.5 dB gain with 33%
power-added efficiency at 22 dBm output.This power amplifier has excellent linearity while meeting 802.11g spectrum mask requirements up to 22 dBm. The
device typically consumes only 95 mA total current at 18 dBm output power, with
linear 54 Mbps 802.11g modulation. This efficiency is desirable in embedded
applications such as in hand-held units. The SST12LP14E also features easy,
board-level usage along with high-speed power-up/-down control through a single
combined reference voltage pin and is offered in both 6- and 8-contact XSON
packages.
