Abstract
The frequency response, particularly the chirp characteristics of W-band waveguide mounted IMPATT devices operating with a variable load has been investigated analytically in this work. The measured chirp bandwidth agrees satisfactorily with the computed value based on the proposed device-circuit interaction model.
