SKA-6039033030-1212-AP

Rev. 1.1

Description:
Model SKA-6039033030-1212-AP is an E-Band, PIN diodebased electrical attenuator. The attenuator exhibits 2.5 dB
typical insertion loss and 25 dB nominal attenuation acrossthe frequency range of 60 to 90 GHz. The control voltage ofthe standard model is 0 to +5 VDC with a typical current
draw of 5 mA. However, the attenuator can also be
configured with negative control voltage from 0 to -5 VDC.
The control speed of the attenuator can go up to 100 ns.
The RF input and output ports are WR-12 wavguides withUG-387/U flanges, and a female SMA coaxial connector
provides the control signal.

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 waveguide will cause performance degradation and possible device
damage.
• Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
