Abstract
A microwave oscillator with TM01.delta. dielectric resonator is disclosed. The oscillator operates with a TM01.delta. mode as contrasted with prior art techniques of TE01.delta. mode. This provides for an improved tuning range in excess of 10% of the operating frequency.
Claims9
A microwave oscillator comprising
- a tubular dielectric resonator operating in a TM01.delta. mode and having a resonant oscillation frequency,
- an adjustable dielectric tuning rod located coaxially to said resonator for tuning to the resonant frequency of said resonator, said resonator and said tuning rod having similar dielectric properties, and
- a metal housing for supporting said resonator and said tuning rod.
A microwave oscillator comprising
- tubular dielectric resonator means operating in a TM01.delta. mode and dielectric tuning rod means located coaxially to said resonator for tuning to the resonant frequency of said resonator, wherein said resonator means and said tuning rod means have similar high-permittivity temperature compensated dielectric properties.
