BLA6H1011-600,112

Overview

The BLA6H1011-600 is a 600 W LDMOS pulsed power transistor designed for TCAS and IFF applications in the 1030 MHz to 1090 MHz range. It operates at a supply voltage of 48 V with an IDq of 100 mA, delivering 600 W output power, 17 dB power gain, and 52% efficiency under typical pulsed RF conditions (tp = 50 µs, δ = 2%). The device features a flanged balanced ceramic package (SOT539A) with two mounting holes and four leads. Key electrical limits include a drain-source voltage of 100 V, gate-source voltage up to 13 V, and a junction temperature maximum of 200 °C.
