SST Communications, a developer of RF front-end components and modules for a wide range of wireless applications has announced that it has doubled the output power of its 2.4 GHz WLAN power amplifier (PA) offering with the new SST12CP11. Housed in a compact 3 x 3mm QFN package, the three-stage device achieves 34 dB power gain, 26 dBm 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. With its ultra-high linear output power, the SST12CP11 helps increase the transmission range and data rate of 802.11b/g/n wireless access points and routers in consumer and enterprise environments.

“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,” said Daniel Chow, president, SST Communications. “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 ultra-high linear output power capability. In addition, the device is 802.11b/g spectrum mask compliant up to 29 dBm for added performance. Like all of SST Communications’ PAs, the SST12CP11 is manufactured using a reliable InGaP/GaAs HBT technology. The high performance of the SST12CP11 enables wireless network system designers to provide robust WiFi operation in challenging RF environments where building materials and floor plan layouts are often not conducive to RF performance.

The SST12CP11 is the latest addition to SST Communications’ broad range of WiFi power amplifier products, which include high-efficiency and high-gain designs for embedded and high-performance WLAN applications. Every WiFi PA from SST Communications provides an on-chip, high dynamic range and temperature-stable power detector that eliminates the need for external detector circuitry.
