Microsemi 0912-25: 960–1215 MHz Pulsed Avionics RF Transistor Notes

0912-25 is an NPN RF transistor aimed at pulsed avionics work in the 960–1215 MHz L-band window. Summary specs include about 55 V VCEO, 8.5–10 dB gain, up to 125 W power, 2.5 A Ic, and a 55CT chassis package with TJ to 200 °C. Pulsed L-band stages need careful duty-cycle derating, VSWR protection, and a solid RF ground to the flange. Cross-check related Microsemi avionics power devices (TAN-class neighbors) when the exact power tier changes. Qualify date codes and packaging carefully on secondary-market lots; RF power transistors are frequent targets for remarking. Match the 55CT footprint and bolt torque to the datasheet drawing.
