ABSTRACT:
Disclosed is a means for obtaining a high Q oscillator which is compact and s adapted to be readily incorporated into known forms of microwave integrated circuits, e.g. a parametric amplifier. The oscillator which for example may comprise a pump oscillator for a parametric amplifier includes efficient means for coupling to microstrip without destroying the high Q of the oscillator circuit. The negative resistance elements which may be, for example, a Gunn diode, IMPATT diode or the like is located in a resonator cavity which is a combination of radial transmission line cavity and a rectangular waveguide cavity.
