SOF-1003-M1

Rev. 1.2

Description:
Model SOF-1003-M1 is a W-Band, wide mechanicaltuning bandwidth Gunn oscillator that utilizes a highperformance GaAs Gunn diode and proprietary cavity
design to deliver 0 dBm typical power with low AM/FM
noise and harmonic emissions. The oscillator has a center
frequency of 100 GHz and a mechanical tuning range of±10 GHz. Compared to its multiplier-based counterparts,
the Gunn oscillator is a lower cost alternative and acleaner source. The Gunn oscillator is equipped with amicrometer for quick frequency tuning when used as abench top unit. Models with a self-locking set screw for frequency tuning are available under a different
model number for use in system integration applications. The performance of the oscillator can befurther enhanced by adding an optional integrated isolator, Gunn oscillator modulator/regulator, andtemperature heater.

All data presented is collected from a sample lot. It is for illustration only. Actual data varies unit
to unit.
The data given above was tested under case temperature +35 ° C.
Always set micrometer reading to around 100 GHz when turning on the oscillator to ensure correctmode operation.
SAGE Millimeter Gunn oscillator regulator, model SOR-R3, is highly recommended to prevent theGunn oscillator damage due to possible over voltage and/or reverse bias. The outline of theregulator is shown in the appendix section below.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

Caution:•••••Reversing polarity will destroy the device.
Bias voltage should not exceed +5.5 Volts.
The case temperature of the device should not exceed +55 ˚C. Use an additional heatsink or fan
if necessary.
When handling coax connectors, proper torque, 8.0 ± 0.4 inch-pounds (0.90 ± 0.02 Nm), should
be applied. SAGE Millimeter torque wrench, model SCH-08008-S1, is highly recommended.
Any foreign objects in the waveguide will destroy the device.
