Transistors

The high power pulsed transistor device part number IB0912M500 is designed for systems operating over the instantaneous bandwidth of 960-1215 MHz. While operating in class C mode under TACAN pulsing conditions and Vcc=50V, this common base device supplies a minimum of 500 watts of peak pulse power. It utilizes a low loss internal input impedance matching structure to yield maximum device gain and to ease the implementation of external matching circuitry. The new generation bipolar transistor geometry utilizes a gold metallization system to achieve maximum reliability. Emitter ballast resistance is incorporated on the active cell for optimum thermal distribution and maximum reliability. All transistors are 100% screened for large signal RF parameters.
