p-band High Gain Power Transistor with 150 W Pulsed Output

Using the novel technologies such as so-called dual emitter ballastingof microwave power transistor and As-doped polysilicon emitter tree overlay structure, the practicable pulsed power transistor used for engineering has beendeveloped. The transistor is a 16-cell device with peak output power of 150 W at500 μs pulse width, 15 percent duty cycle, high gain of 10 dB and 50 percent collector output efficcncy over a (540-610) MHz band.
