The SST12CP12 high-power amplifier

The SST12CP12 is a 2.4-GHz RF high-power amplifier that adds support for 256-QAM ultra-high data rate modulation. With its high linear output power, this amplifier significantly extends the range of IEEE 802.11b/g/n WLAN systems while providing excellent power at the maximum 256-QAM data rate. The amplifier is also spectrum-mask compliant up to 28.5 dBm for 802.11b/g communication and utilizes orthogonal frequency-division multiplexing (OFDM) to correct severe channel conditions without using complex equalization filters.

The SST12CP12 power amplifier has a 380mA at 23 dBm low operating current, which enables more transmission channels and a higher data rate for each system. The amplifier also features easy to use 50-Ω on-chip input match and simple output match. In addition, the integrated linear power detector provides temperature stability and immunity to voltage standing wave ratio (VSWR) radio-wave reflection to provide accurate output power control.

The SST12CP12 costs $0.97 each, in 10,000-unit quantities. It ships in a 3-mm × 3-mm × 0.55-mm, 16-pin QFN package.
