2.4 GHz High-Power, High-Gain Power Amplifier
A Microchip Technology Company
SST12LP15B
Product Brief
The SST12LP15B is a versatile power amplifier based on the highly-reliable
InGaP/GaAs HBT technology. Easily configured for high-power applications with
excellent power-added efficiency while operating over the 2.4- 2.5 GHz frequency
band, it typically provides 32 dB gain with 34% power-added efficiency. The
SST12LP15B has excellent linearity while meeting 802.11g spectrum mask at 24
dBm. The SST12LP15B 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 a 16-contact VQFN package.
Features
? High Gain:
– More than 32 dB gain across 2.4–2.5 GHz over tempera-
ture -40°C to +85°C
? High linear output power (at 3.3V):
– >29 dBm P1dB
– Meets 802.11g OFDM ACPR requirement up to 26 dBm
– ~3% added EVM up to 22 dBm for 54 Mbps 802.11g
