Abstract
A microwave oscillator having a dielectric resonator, in particular for use in the 22 GHz range, the oscillator comprising a negative resistance component (18) and a dielectric resonator (19) disposed on the surface of a substrate (13, 14) situated inside a housing (10), and the housing (10) being provided with a clearance situated over the dielectric resonator (19).
Claims10
A microwave oscillator having a dielectric resonator, in particular for use in the 22 GHz range, said oscillator comprising:
- a housing, a substrate situated in said housing, a negative resistance component and a dielectric resonator disposed on a surface of said substrate, said housing including a chimney extending perpendicular to the surface of the substrate and providing a clearance over the dielectric resonator, said chimney being tapped on the inside surface thereof, and a double threaded, hollow screw having internal and external threads, said hollow screw being threaded in said chimney, and an adjustable self-locking screw, screwed in the hollow screw.
