Gunn Diode Oscillator Circuit. Gunn diodes are used to build oscillators for generating microwaves with frequencies ranging from 10 ghz to thz. Gunn its largest use is in electronic oscillators to generate microwaves in applications such as radar speed guns microwave.
And this is termed as biasing the diode into negative resistance region. How a gunn diode works as an oscillator dc bias. At microwave frequencies it is found that the dynamic action of the diode incorporates elements resulting from the thickness of the active region.
A dc voltage source vb biases the diode into its negative resistance region and provides power.
