94 GHz varactor tuned oscillator suits 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.
