STA-60-12-D1

Final Rev 1.3

Description:
Model STA-60-12-D1 is a general purpose direct reading, rotary vaneattenuator for use in millimeter wave systems across the standard Eband frequency range of 60 to 90 GHz. The attenuator has a large
scale calibrated dial which indicates the attenuation value directly.
The attenuator is an ideal piece of equipment in waveguide systems
where a broad direct reading of attenuation is required. The
attenuator exhibits exceptional repeatability during frequentattenuation setting operations. The attenuator exhibits 0.7 dB typical insertion loss and up to maximum
60 dB attenuation. The accuracy of the attenuator is 0.1 dB or 3% of the reading, whichever is larger, up
to 40 dB, 5% up to 50 dB, and “for reference only” above 50 dB.

Note:• Calibration accuracy is 0.1 dB or 3% of the reading, whichever is greater, for attenuation ranges
up to 40 dB, 5% up to 50 dB, and “for reference only” above 50 dB.
• All calibration and testing are performed at +25 °C room temperature.
• This product is intended to be used in a controlled lab environment. To ensure best possible
accuracy and prevent unintended behavior, please operate the unit as close to +25 °C roomtemperature as possible.
• The attenuation flatness is ±2% or ±0.5 dB of the indicated value, whichever is greater, for thefrequency band.
• The phase shift value does change while varying the attenuation.
• 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.
• Eravant reserves the right to change the information presented without notice.
• Other mechanical configurations are available under different model numbers.
Caution:• Exceeding absolute maximum ratings shown will damage the device.
• Any foreign objects in the waveguide will cause performance degradation and may damage thedevice.
