BLC10G27LS-320AVTZ

Overview

The BLC10G27LS-320AVTZ is a 320 W LDMOS asymmetrical Doherty power transistor designed for base station applications in the 2500 MHz to 2700 MHz frequency range. It features a drain-source voltage of 65 V, a junction temperature rating up to 225 °C, and a thermal resistance from junction to case of 0.24 K/W. The device operates with a typical power gain of 15.4 dB and drain efficiency of 42% at 50 W output power under 1-carrier W-CDMA conditions. Packaged in an SOT1258-1 air cavity plastic earless flanged package, it includes integrated ESD protection and video decoupling leads.
