The Model SOV-94306310-10-G1 W-Band Varactor tuned Gunn oscillator from SAGE Millimeter is ideal for radar and test applications.

It utilizes a high-performance GaAs Gunn diode and proprietary cavity design to deliver +13 dBm typical power. The oscillator features a Varactor tuning range of ±3 GHz and delivers low AM/FM noise and harmonic emissions. Compared to its counterparts, such as multiplier based sources, the Gunn oscillator is a lower cost and cleaner source.

The center frequency of the oscillator can be mechanically trimmed within ±100 MHz using the self-locking set screw.  The performance of the oscillator can be further enhanced by adding an isolator, Gunn oscillator modulator/regulator and temperature heater.

Key features include low AM/FM noise and harmonics; mechanical frequency trimming; and broad tuning bandwidth. Typical applications include test sources, signal generation, FMCW radar systems and communication systems.
