SOM-77302320-12-S1Model SOM-77302320-12-S1 is a free running E band mechanically tuned Gunn oscillator with output power 20 dBm and tuning bandwidth +/- 1 GHz. The mechanical tuning is accomplished via a self-locking tuning screw or micrometer. The bias voltage and current to operate the oscillator is at +10 Vdc and 200 mA typically. The oscillator is also bias tunable to allow frequency modulation via its bias port.

While the oscillator exhibits moderate frequency stability, an optional heater can be installed to further improve the temperature performance with a single bias at +10 Vdc to supply heating power up to 5 watts. The mechanically tuned Gunn oscillator family also includes the models to cover Q, U, V and W band.
