Abstract :
The paper proposes to stabilize the oscillation frequency through direct interaction of the Gunn diode with a whispering gallery mode (WGM) dielectric resonator (DR). The dimensions of a WGM resonator can be much larger than the operating wavelength, and therefore less sensitive to fabrication tolerances. In order to transmit the generated mm-wave signal to an external load, the structure is coupled to the DR. The proposed configuration is structurally capable to be integrated with three dimensional waveguide structures such as DIG or planar guiding like CPW or microstrip line.
