ABSTRACT:
A stabilization system for IMPATT diode microwave oscillators, comprising: means for electrical and mechanical support of said IMPATT diode, forming the return conductor of the feeding, the thermal dissipator and the terminal of a transmission line; a power supply feeding conductor for said diode comprising a substantially filamentary conducting element, inductively associated for a portion thereof to a ferrite, said ferrite being characterized in having high losses in the frequency spectrum where spurious oscillations might appear, and practically neglectable losses at the operating frequencies of said IMPATT diode.
