26.5 to 40 GHz, 0 to 70 dB, WR-28 Waveguide, Ka Band Programmable Attenuator
- 1 Week ARO
Model STA-60-28-P1 is a motorized, programmable rotary vane attenuator for use in millimeterwave systems across the standard Ka-band frequency range of 26.5 to 40 GHz. The attenuation control is an IEEE-488 (GPIB) and USB port 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.
