SKA-1834033537-KFKF-A1-M

Rev. 1.0

Description:
Model SKA-1834033537-KFKF-A1-M is MMIC based electricalattenuator. The attenuator exhibits 3.5 dB typical insertion loss
and 0 to 37 dB nominal attenuation range across the frequency
range of 18 to 40 GHz while applying 0 to -3 VDC control voltage.
While the control voltage of the standard model is 0 to -3 VDC, themaximum damage control voltage is - 5 VDC. The RF input andoutput ports are K(F) connectors, and the control port is withSMA(F) connector.

Note:

All data presented is collected from a sample lot. Actual data may vary unit to unit.
All testing was performed under +25˚C case temperature.
Other mechanical configurations are available under different model numbers.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

Caution:

Exceeding absolute maximum ratings shown will damage the device.
The attenuator is a static sensitive device. Always follow ESD rules when working with theattenuator.
Any foreign objects in the attenuator will cause performance degradation and possible device
damage.
Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
