ATF-50189 is a high linearity, medium power, low noise E-pHEMT FET packaged in a low cost surface mount SOT89 package. The combination of low noise figure and high output IP3 at the same bias point makes it ideal for receiver and transmitter application. Its operating frequency range is from 400 MHz to 3.9 GHz. The ATF-50189 is ideally suited for Cellular/PCS and WCDMA wireless infrastructure, WLAN, WLL and MMDS application, and general purpose discrete E-pHEMT amplifiers which require high linearity and power. All devices are 100% RF and DC tested.
