BLA6H0912-500,112

Overview

The BLA6H0912-500 is a 500 W LDMOS power transistor designed for avionics transmitter applications in the 960 MHz to 1215 MHz range. It supports Mode-S, TCAS, JTIDS, DME, and TACAN systems. Typical pulsed RF performance at 960 MHz to 1215 MHz with a 50 V supply and 100 mA quiescent current yields 450 W output power, 17 dB gain, and 50% efficiency. The device features integrated ESD protection and high ruggedness against load mismatches up to 10:1 VSWR. It utilizes an internally matched design within a flanged ceramic SOT634A package.
