SOM-90304316-10-M1

Rev. 1.0

Description:
Model SOM-90304316-10-M1 is a W-Band, mechanically tuned
Gunn oscillator that utilizes a high-performance GaAs Gunn
diode and proprietary cavity design to deliver +16 dBm typicalpower. The oscillator features a frequency tuning range of 88 to
92 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 Gunn
oscillator’s frequency can also be tuned by varying the bias voltage, which is useful for phase-locking andelectrical-tuning applications. The Gunn oscillator is equipped with a micrometer for quick frequency
tuning and test bench applications. Models with a self-locking set screw for system integration areavailable under a different model number. The performance of the oscillator can be further enhancedby adding an optional isolator, Gunn oscillator modulator/regulator and temperature heater.

The data given above was tested under case temperature +25 °C.
The SAGE Millimeter Gunn oscillator regulator SOR-R3 is highly recommended for over voltage andreverse bias protection. The outline of the model SOR-R3 is shown in the appendix
The optional AM/FM Modulator SOR-M3 can be ordered separately to further enhance thefunctionality of the Gunn oscillator. The outline of the modulator is also shown in the appendix.
The bias tuning feature can be used for electrical tuning and phase lock loop applications.

Caution:••••••

Reversing polarity will destroy the device.
Bias voltage should never exceed +5.0 Volts.
The oscillator is factory set to operate around 90.0 GHz. The self-locking set screw is for frequency
trimming only. It is not designed for frequent frequency tuning.
The case temperature of the device should never exceed +50 ˚C. Use an additional heatsink or fan ifnecessary.
Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should be applied. SAGE Millimeter torquewrench, model SCH-08008-S1, is highly recommended.
Any foreign objects in the waveguide will destroy the device.
