Power amplifier has 'ultra-high' linear output power

The SST12CP11 is housed in a 3 x 3mm QFN package, and according to SST, the three stage device achieves 34dB power gain, 26 and 25 dBm linear output power at 3.5% and 2.5% EVM, respectively, at 5.0V bias with less than 470 mA current consumption. It has been designed to help increase the transmission range and data rate of 802.11b/g/n wireless access points and routers in consumer and enterprise environments. Daniel Chow, president, SST Communications, said: "As a premier high volume supplier of PAs to the WiFi industry, we are continuously improving our product offering to meet the evolving demands of wireless users. With our new SST12CP11, we are delivering an ultra high power, robust linear PA that will help increase the broadcast range of wireless AP/routers to better support broadband applications, such as streaming video and other multimedia-rich content." The SST12CP11 supports an operating voltage up to 5V, resulting in what is described as an ultra high linear output power capability. The device is 802.11b/g spectrum mask compliant up to 29dBm and is manufactured using InGaP/GaAs HBT technology. According to SST, the high performance of the SST12CP11 enables wireless network system designers to provide robust WiFi operation in challenging rf environments.
