Figure 1: Schematic construction of a gunn-oscillator in waveguide-technology

Figure 1 shows the schematic construction of a gunn-oscillator in waveguide-technology. The distance between the Gunn- Diode and the sliding short-circuit-element shall to be λ/4. The iris and the conductive screw are used for impedance matching in the waveguide.

The gunn oscillator can deliver continuous power up to about 65 milliwatts and pulsed outputs of up to about 200 watts peak.
