High-power RF amplifier

17 September 2014 Analogue, Mixed Signal, LSI

Microchip’s latest 2,4 GHz high-power amplifier – the SST12CP21 – offers ultra-low EVM (error vector magnitude) and current consumption for 256-QAM and IEEE 802.11n systems.

It delivers high linear output power of up to 23 dBm at 1,75% dynamic EVM, with MCS9 HT 40 MHz bandwidth modulation at 5 V and 320 mA current consumption.

Additionally, the chip delivers 25 dBm linear power at 3% EVM with only 350 mA current consumption for 802.11g/n applications. 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 for 802.11b/g communication.

Board space is reduced by the small 3 x 3 x 0,55 mm, 16-pin QFN package that matches a popular pin-out. This amplifier also features 50 Ω on-chip input match and simple output match, which is easy to use and reduces board size. Additionally, the integrated linear power detector provides accurate output power control over temperature and 2-to-1 output mismatch.
