BLF8G24LS-100GVJ

Overview

The BLF8G24LS-100GVJ is a 100 W LDMOS power transistor designed for base station applications in the 2300 MHz to 2400 MHz frequency range. It features decoupling leads that provide an improved video bandwidth of 90 MHz typical, supporting low memory effects and excellent pre-distortability. The device operates with a drain-source voltage of 28 V and a quiescent current of 900 mA, delivering 25 W average output power with 19 dB gain and 32% drain efficiency under two-carrier W-CDMA conditions. It utilizes an earless flanged ceramic package (SOT1244C) and includes integrated ESD protection.
