mm-wave evanescent mode oscillator
Abstract
Design and performance features of mm-wave evanescent mode waveguide (EMWG) oscillators are summarized. EMWGs supply passbands below the cutoff point and are known to store magnetic energy. If capacitive elements such as Gunn or IMPATT diodes are added to the lumped element oscillator resonance conditions arise and are tuned by matching diode and load impedances, transferring the EMWG signal to a series or shunt load and by selecting the biasing arrangement. Tests results are provided for 30 and 40 GHz oscillators.
