F-Band Programmable Attenuator, Limited Run

This is a Limited Run model, so inventory may not be restocked. Customers who anticipate long-term requirements should consider STA-60-08-S1 as an alternative solution. Read more about Limited Run Products here.

STA-60-08-P1 is a motorized, programmable rotary vane attenuator for use in millimeterwave systems across the standard F-band frequency range of 90 to 140 GHz. The attenuation control is an IEEE-488 (GPIB) and USB interface to accommodate remote operations from 0 to 70 dB. Attenuation increments are 0.05 dB between 0 and 20 dB and 0.1 dB between 20 and 70 dB. On the front panel, a local adjustment switch and digital readout allow for convenient manual operations. When used remotely, the local switch can be locked to prevent inadvertent adjustments. The motor control and interface circuits are custom designed and uniquely packaged within the attenuator housing. The microprocessor based electronics ramp the speed of a precision stepper motor to ensure fast and accurate positioning.
