SOM-90302317-10-M1

Rev. 1.0

Description:
Model SOM-90302317-10-M1 is a W-Band, mechanically tuned
Gunn oscillator that utilizes a high-performance GaAs Gunn
diode and proprietary cavity design to deliver +17 dBm typicalpower. The oscillator features a frequency tuning range of 89 to91 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.

Note:•••••••All data is presented using a limited sample lot, actual data may vary unit to unit.
The data given above was tested under case temperature +35 °C.
Always set micrometer reading to approximately 90.0 GHz when turning on the oscillator to avoid
wrong mode operation.
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 below.
The bias tuning feature can be used for electrical tuning or FM modulation and phase lock loop
applications.
AM modulation can be achieved by turn on/off the oscillator via bias port with the modulation rateup to 1 kHz.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

Caution:•••••Reversing polarity will destroy the device.
Bias voltage should never exceed +5.0 Volts.
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.
