BLA9H0912L-700U

Overview

The BLA9H0912L-700U is a 700 W LDMOS power transistor designed for avionics applications in the frequency range from 960 MHz to 1215 MHz. It operates with a drain-source voltage of 50 V and delivers a typical power gain of 20 dB at an output power of 700 W. The device features a flanged ceramic package (SOT502A) with two mounting holes and two leads. Key electrical characteristics include a drain-source breakdown voltage of 106 V, a gate-source threshold voltage ranging from 1.5 V to 2.5 V, and a maximum junction temperature of 225 °C. It exhibits excellent ruggedness, capable of withstanding a load mismatch corresponding to VSWR = 20:1 through all phases.
