Abstract: The modulation sensitivity, linearity, and FM noise performance of a mm IMPATT oscillator is described. It is shown that when the oscillator is FM modulated with short rise time pulses, the ...

Abstract: Recent experimental results on impact avalanche transit-time diode oscillators fabricated by ion implantation are presented. The technique and problems involved are given. The diodes gave CW ...

An IMPATT diode (impact ionization avalanche transit-time diode) is a form of high-power semiconductor diode used in high-frequency microwave electronics devices. They have negative resistance and are ...
