2.4 GHz RF High-Power Amp Extends Ultra-High Data Rate WLAN Range

The SST12CP21, Microchip’s latest 2.4 GHz RF high-power amplifier, offers ultra low EVM and current consumption for 256-QAM and IEEE 802.11n systems. The amplifier delivers high linear output power of up to 23 dBm at 1.75% dynamic EVM, with MCS9 HT40 MHz bandwidth modulation at 5 V and 320 mA current consumption. Additionally, the device delivers 25 dBm linear power at 3% EVM with only 350 mA 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 power amplifier has an operating current of 320 mA at 23 dBm and 350 mA at 25 dBm, is spectrum mask compliant up to 28 dBm for 802.11b/g communication, and also features 50 Ω on-chip input match and simple output match. Priced at $0.754 each/10,000, the SST12CP21 RF high-power amplifier is available now for sampling and volume production in a 3 x 3 x 0.55 mm 16-pin QFN package. Evaluation boards are also available.
