Bias Circuit

2.4 GHz High-Power, High-Gain Power Amplifier

SST12LP07A

The SST12LP07A is a versatile power amplifier based on the highly-reliable InGaP/

GaAs HBT technology. It is easily configured for high-power applications with excel-

lent (30.8%) power-added efficiency, operating over the 2.4- 2.5 GHz frequency band

and meeting 802.11 b/g spectrum mask at 23.5 dBm. The SST12LP07A has excellent

linearity, typically ~2.5% added EVM at 20 dBm output power, which is essential for 54

Mbps 802.g/n operation. The Power Amplifier has an excellent on-chip, single-ended

power detector, providing a reliable solution to board-level power control. The

SST12LP07A is offered in a 12-contact XQFN package.
