Abstract
A microwave solid-state oscillator includes a casing hermetically enclosing a microwave oscillation device and a dielectric resonator electromagnetically coupled with the microwave oscillation device, an output terminal leading out an oscillation output from said casing, and a microwave terminal electromagnetically coupled to the dielectric resonator, one end of which is connected to a microwave line having a terminating admittance at the outside of the casing.
Claims11
A microwave solid-state oscillator for producing an oscillation output, said oscillator comprising:
- a microwave oscillation device circuit;
- a dielectric resonator electromagnetically coupled with said microwave oscillation device circuit;
- a casing comprised of a cap and a stem for hermetically enclosing said microwave oscillation device circuit and said dielectric resonator;
- an output terminal for said oscillation output leading out from said casing, said terminal having an end positioned within said casing, said end being electromagnetically coupled to said dielectric resonator;
- and
- a microwave line comprised of an inner portion positioned within said casing, said inner portion being electromagnetically coupled to said dielectric resonator and an outer portion positioned out of said casing said outer portion including an adjustable terminating admittance means for adjusting said output of said oscillator.
