Model SE2568U is a high-performance power amplifier developed by SiGe Semiconductor for the embedded 2.4-GHz wireless local area network (WLAN) market. It is designed for simple integration with battery-powered circuits and provides +18 dBm output power with 3-percent error-vector-magnitude (EVM) performance. It incorporates an impedance matched power amplifier, power detector, 3.2-GHz local oscillator (LO) filter and harmonic filter in a QFN package measuring just 2.0 x 2.0 x 0.5 mm. The CMOS-compatible amplifier is designed for use with supplies from +2.7 to +4.8 VDC. It draws just 120 mA current when delivering +18 dBm output power.

According to Sanjiv Shah, the firm's Director, Product Marketing WiMAX, & Embedded WLAN, "Current solutions require up to 15 external components for matching and filtering to get equivalent performance, but the SE2568U PA requires only three external capacitors. This significantly reduces device and bill of materials and board assembly costs as well as the overall system footprint, all of which are paramount in embedded applications."
