QFN packaged 5 GHz amp yields up to 24 dBm

The SST11CP22 5.1 to 5.9 GHz power amplifier module targets IEEE 802.11ac high data rate Wi-Fi applications. The module delivers 19 dBm linear output power at 1.8% dynamic error vector magnitude (EVM) with MCS9 80 MHz bandwidth modulation. 

The device yields 20 dBm linear power at 3% EVM for 802.11a/n applications, is spectrum mask compliant up to 24 dBm for 802.11a communication, and has less than -45 dBm/MHz RF harmonic output at this output power, making it easier to meet FCC regulations. It comes in a 4 x 4 mm 20-pin QFN package, includes a output harmonic rejection filter, and is 50 Ω matched. The IC needs only four external components. $0.92 each in 10,000.
