In August 2014, Microchip Technology Inc announced its latest 2.4GHz 256 QAM RF high power amplifier, the SST12CP21, which offers ultra low EVM and a current consumption for 256 QAM and IEEE 802.11n systems. The SST12CP21 delivers high linear output power of up to 23dBm at 1.75 per cent dynamic EVM, with MCS9 HT40MHz bandwidth modulation at 5V and 320mA current consumption. Additionally, the SST12CP21 delivers 25dBm linear power at 3 per cent EVM with only 350mA current consumption for 802.11g/n applications. This performance significantly extends the range of 802.11b/g/n WLAN and MIMO systems, while consuming extremely low current at the maximum 256 QAM data rate. The SST12CP21 is also spectrum mask compliant up to 28dBm for 802.11b/g communication. Board space is reduced by the small 3×3×0.55 mm, 16-pin QFN package that matches a popular pin out. The SST12CP21 power amplifier has a low operating current of 320mA at 23dBm and 350mA at 25dBm, which enables multichannel and higher data rate WLAN systems. This amplifier also features 50 ohm on chip input match and simple output match, which is easy to use and reduces board size.
