HIGHHFREQUENCY TRANSISTOR INVERTER

摘要

PURPOSE:To effectively lower inverse voltage between a base and emitter of a transistor by means of a condenser connected to both the base and the emitter at a diode which enables only inverse direction by-pass against the high frequency. CONSTITUTION:When a transistor 6 is cut off, the charging charge of a condenser 9 is discharged through a resistance 10 while being bypassed in the inverse direction by a capacity generated between the junction of a diode 13 to high frequency, and partially charged by the capacity formed at a condenser 12 and the both ends of the diode 13. Thus, inverse voltage applied between a base and emitter of the transistor 6 depends upon only the terminal voltage of the condenser 12, and consequently inverse voltage between the base and emitter of the transistor 6 can sufficiently be lowered.
