SOM-75310316-12-M1

Advanced

Description:
Model SOM-75310316-12-M1 is an E-Band,wide mechanical tuning bandwidth Gunn
oscillator that utilizes a high-performance
GaAs Gunn diode and proprietary cavity
design to deliver +16 dBm typical powerwith low AM/FM noise and harmonic
emissions. The oscillator has a center
frequency of 75 GHz and a mechanicaltuning range of ±5 GHz. It utilizes afundamental Ka band broad tuning
bandwidth Gunn oscillator and an active x2
multiplier to reach 70 to 80 GHz with +16
dBm output power. The Gunn oscillator isequipped with a micrometer for quick frequency tuning when used as a bench top unit. Models with aself-locking set screw for frequency tuning are available under a different model number for use insystem integration applications. The performance of the oscillator can be further enhanced by adding an
optional integrated isolator, Gunn oscillator modulator/regulator, and temperature heater.

Note:• 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 75.0 GHz when turning on the oscillator to ensure correctmode operation.
• Eravant Gunn oscillator regulator, model SOR-R3, is highly recommended to prevent the Gunn
oscillator damage due to possible over voltage and/or reverse bias. The outline of the regulator isshown in the appendix section below.
• Eravant 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 for Ka Band Oscillator and +15 Volts for E band
Multiplier. However, a common +8.0 Volts bias can be used if the regulator SOR-R3 is used.
The case temperature of the device should not exceed +50 ˚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. Eravant torque wrench, model SCH-08008-S1, is highly recommended.
Any foreign objects in the waveguide will destroy the device.
