2.4 GHz High-Power, High-Gain Power Amplifier
SST12LP14A
A Microchip Technology Company
Data Sheet
SST12LP14A is a versatile power amplifier based on the highly-reliable InGaP/
GaAs HBT technology. Easily configured for high-power applications with good
power-added efficiency while operating over the 2.4-2.5 GHz frequency band, it
typically provides 29 dB gain with 23% power-added efficiency at 22 dBm.
SST12LP14A has excellent linearity while meeting 802.11g spectrum mask at 23
dBm. The excellent on-chip power detector provides a reliable solution to boardlevel power control. SST12LP14A is offered in 16-contact VQFN package.
