Abstract :
A lumped equivalent circuit is proposed to characterise the load impedance presented to a Gunn device mounted in a waveguide cavity. Using analytical expressions for the elements of the circuit, theoretical predictions for the properties of Gunn oscillators with and without a coupling iris are made, and are compared with experiments.
