2.4 GHz High-Power, High-Gain Power Amplifier - SST12LP18E

2.4 GHz High-Power, High-Gain Power Amplifier
SST12LP18E
A Microchip Technology Company
Product Brief
The SST12LP18E is a versatile power amplifier based on the highly-reliable InGaP/
GaAs HBT technology. The SST12LP18E is a 2.4 GHz high-efficiency Power Amplifier designed in compliance with IEEE 802.11b/g/n applications. It typically provides
25 dB gain with 32% power-added efficiency. The SST12LP18E has excellent linearity while meeting 802.11g spectrum mask at 21.5 dBm. The SST12LP18E is ideal for
embedded applications because it provides linear power evan at low-battery voltages. With a reference voltage as low as 2.7V, the SST12LP18E will operate from
-20°C to +85°C and is offered in a 8-contact XSON package.
