BLC9G20XS-550AVTY

Overview

The BLC9G20XS-550AVT is a 550 W LDMOS asymmetric Doherty power transistor designed for base station applications in the 1805 MHz to 1880 MHz frequency range. It features a drain-source breakdown voltage of 65 V and operates with a typical case temperature range from -40 °C to +125 °C. In an asymmetrical Doherty test circuit at VDS = 28 V, it delivers 85 W average output power with 15.4 dB gain and 44.5% drain efficiency using a 1-carrier W-CDMA signal. The device utilizes an SOT1258-4 air cavity plastic earless flanged package.
