Abstract
The components of a transistor oscillator are mounted on an end cap rotatably mounted on the outer tube of a cavity resonator which stabilizes the oscillator. The intensity with which a high frequency is applied to the cavity resonator is adjustable by rotation of the end cap.
Claims7
A high frequency transmitter comprising
- a cavity resonator having an outer tube having spaced opposite ends, a coaxial inner tube spaced from and surrounded by the outer tube and an end cap coaxially rotatably mounted on said outer tube at one end thereof;
- and
- a transistor oscillator stabilized by the cavity resonator and having components mounted on the end cap of said resonator whereby the intensity with which a high frequency is applied to said resonator is adjustable by rotation of said end cap.
