QuinStar’s Mechanically Tunable Gunn Oscillators cover the frequency range of 18 – 150 GHz in nine waveguide bands. They combine a high-Q resonant circuit with either a GaAs or InP Gunn diode. Typically, high-power applications at the higher frequencies use InP diodes. Each oscillator has an internal low-frequency bias circuit with an oscillation suppression network and over-voltage protection. The standard units operate over 0 to 50° C. They incorporate a screw tuner with a reliable self-locking feature.
QuinStar offers a wide range of features. For example, we can provide Gunn oscillators with broader tuning ranges, higher power levels, micrometer tuners, temperature controlled heaters, integral isolators, voltage regulators, modulators, and injection-locking capability. Further, if your application requires higher power, QuinStar offers an amplified version of the oscillators using power amplifiers. Finally, the Mechanically Tunable Gunn Oscillators provide a small bias tuning of operating frequency. Often, bias tuning can be used in place of varactor tuning (QTV).
