SOM-11305210-90-S1-WP

Rev 1.0

Description:
Model SOM-11305210-90-S1-WP is an X-band, mechanically tuned
Gunn oscillator that delivers +12 dBm typical power. The oscillator
features a frequency tuning range of 10.275 to 10.775 GHz and delivers
low AM/FM noise and harmonic emissions. Compared to its
counterparts, such as multiplier-based sources, the Gunn oscillator is alower cost and cleaner source. The Gunn oscillator’s frequency can also
be tuned by varying the bias voltage, which is useful for phase-locking
and electrical-tuning applications. The Gunn oscillator is equipped witha self-locking set screw for frequency trimming. Models with amicrometer for lab and test bench applications are available under adifferent model number. The performance of the oscillator can be further enhanced by adding an
optional isolator, Gunn oscillator modulator/regulator and temperature heater.

Note:• The data given above was tested under case temperature +35 °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 below.
• The bias tuning feature can be used for electrical tuning and phase lock loop applications.

Reversing polarity will destroy the device.
Bias voltage should never exceed +10.0 Volts.
The oscillator is factory set to operate around 10.525 GHz. The self-locking set screw is forfrequency trimming only. It is not designed for frequent frequency tuning.
The case temperature of the device should never exceed +85 ˚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.
