BLC9G20LS-120VY

Overview

The BLC9G20LS-120V is a 120 W LDMOS power transistor designed for base station applications at frequencies from 1805 MHz to 1995 MHz. It features enhanced video bandwidth performance with decoupling leads providing a typical 75 MHz bandwidth. The device operates with a drain-source voltage of 28 V and quiescent current of 700 mA, delivering 30 W average output power with 31% drain efficiency in a two-carrier W-CDMA test circuit. It exhibits excellent ruggedness, capable of withstanding a VSWR of 10:1 through all phases. The transistor is internally matched and housed in an air cavity plastic earless flanged package (SOT1275-1) with six leads.
