Abstract
We demonstrate that free-space oscillations can be used to estimate the opt imum frequency of operation of a heterojunction GaAs/AlGaAs Gunn diode, in terms of efficiency, when the device is placed in a cavity. The variation o f the natural frequency of oscillation with transit region length and poten tial bias has been measured and found to be in good agreement with results from Monte Carlo simulations.
