Product Description

The UP2268 is a RF front end IC integrating high-efficiency, linear power amplifier (PA), switch and low noise amplifier (LNA). Due to the ramp-control feature and a very low current consumption and high P1dB, UP2268 can be used under not only weak signal environment but also strong signal environment. UP2268 is designed for Bluetooth application in the 2.4 GHz ISM bands. The device is packaged in a miniaturized 3mmX3mm, 16 pin QFN with bottom ground.
