Description
An electrically tunable Gunn oscillator designed to
generate RF power in the range of 21.2 to 23.6 GHz. A
Gunn diode and GaAs hyperabrupt varactor diode are
coupled in a single high Q cavity to provide low AM/FM
noise, excellent frequency and power stability with
respect to changes in operating temperature. This VCO
is suitable for both a transmitting source, or the local
oscillator in a receiver assembly in point-to-point
microwave radio systems.
1. Available in 400 MHz electronically tuned bands.
2. Other output power levels are available, consult factory.
3. Specic voltage assigned by factory. Power supply should be held to ±0.10 V.
4. The ambient temperature is dened as air temperature.
5. The frequency band end points per note 1 will be tunable within the tuning voltage range of +1.0 to +13.0 VDC, with sufcient margin to compensate for
the effects of temperature, load, mismatch and aging.
6. A capacitor is supplied between the Gunn bias pin and ground to suppress bias line oscillations.
7. Tuning bias input is SMA-female, solder pin is available, consult factory.
