SOB-94305210-10-S1

Rev. 1.0

Description:
Model SOB-94305210-10-S1 is a W-Band Bias Tuned Gunn
Oscillator that utilizes a high performance GaAs Gunn
diode and proprietary cavity design to deliver +10 dBm
typical power directly with a frequency tuning range of±250 MHz. The oscillator delivers low AM/FM noise andharmonic emissions in the wide mechanical tuning range.
Compared to its counterparts, such as multiplier basedsources, the Gunn oscillator is an alternative lower costand cleaner source. The center frequency of the oscillator can be mechanically trimmed via a self-locking
set screw within ±1.0 GHz frequency range.

All data presented is collected from a sample lot. Actual data may vary unit to unit.
The data given above was tested under case temperature +35 °C.
The bias tuning feature is used for electrical tuning and phase lock loop applications.
The tuning speed can be improved per request.
The mechanical tuning feature is provided for frequency trimming only. To tune the oscillator
more than the specified bandwidth mechanically will damage or degrade the oscillator.
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 +5.5 Volts, otherwise the oscillator will be damages.
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 (0.90 ± 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.
