BLC8G27LS-140AVY

Overview

The BLC8G27LS-140AV is a 140 W LDMOS asymmetrical Doherty power transistor designed for base station applications in the 2496 MHz to 2690 MHz frequency range. It operates at a drain-source voltage of 28 V with a breakdown voltage of 65 V. The device provides a typical power gain of 14.5 dB and achieves a drain efficiency of up to 43% under 1-carrier W-CDMA conditions. It features an air cavity plastic earless flanged package (SOT1275-1) with six leads, including dedicated video decoupling pins.

Feature Summary
