Description
Avago Technologies’s ATF-53189 is a single-voltage high linearity, low noise E-pHEMT FET packaged in a low cost surface mount SOT89 package. The device is ideal as a high-linearity, low noise, medium-power amplifer. Its operating frequency range is from 50 MHz to 6 GHz.
ATF-53189 is ideally suited for Cellular/PCS and WCDMA wireless infrastructure, WLAN, WLL and MMDS application, and general-purpose discrete E-pHEMT amplifers that require medium power and high linearity. All devices are 100% RF and DC tested.
