SOM-70302317-15-S1

Rev. 1.2

Description:
Model SOM-70302317-15-S1 is a V-band, mechanically tuned
Gunn oscillator that utilizes a high-performance GaAs Gunn diodeand proprietary cavity design to deliver +17 dBm typical power.
The oscillator features a frequency tuning range of 69 to 71 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’sfrequency can also be tuned by varying the bias voltage, which isuseful for phase-locking and electrical-tuning applications. The Gunn oscillator is equipped with a selflocking set screw for frequency trimming. Models with a micrometer for lab and test bench applications
are available under a different model number. The performance of the oscillator can be further
enhanced by adding an optional isolator, Gunn oscillator modulator/regulator and temperature heater.

Note:• All data presented is collected from a sample lot. Actual data may vary unit to unit.
• All testing was performed under +35 °C case temperature.
• 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 below.
• The bias tuning feature can be used for electrical tuning and phase lock loop applications.
• 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 +6.0 Volts.
• The oscillator is factory set to operate around 70 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 ± 0.4 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter torquewrench, model SCH-08008-S1, is highly recommended.
• Any foreign objects in the waveguide will destroy the device.
