Ramped for 256-QAM and 802.11b/g/n apps, the SST12CP21 2.4-GHz, 256-QAM RF power amplifier boasts ultra-low EVM and current consumption. It delivers a linear output power up to 23 dBm at 1.75% dynamic EVM with MCS9 HT40-MHz bandwidth modulation at 5V and 320 mA current consumption. Additionally, the amp delivers 25 dBm of linear power at 3% EVM with a current consumption of 350 mA. According to the company, this performance extends the range of 802.11b/g/n WLAN and MIMO systems while consuming low current at the maximum 256-QAM data rate. The SST12CP21 is also spectrum-mask compliant up to 28 dBm. Available in a 16-pin, 3 mm x 3 mm x 0.55 mm QFN package, pricing is $0.754 each/10,000. Evaluation boards are also available.
