2.4 GHz Power Amplifier
SST12LP14
A Microchip Technology Company
Data Sheet
The SST12LP14 is a high-performance power amplifier IC based on the highlyreliable InGaP/GaAs HBT technology. Easily configured for high-power, high-efficiency applications with superb power-added efficiency, it typically provides 30 dB
gain with 22% power added efficiency. The SST12LP14 has excellent linearity
while meeting 802.11g spectrum mask at 23 dBm.It is ideal for the final stage
power amplification in battery-powered 802.11g/b WLAN transmitter applications,
and is offered in 16-contact VQFN package.
