The model PAT-75110-1010 is a W-band programmable attenuator used in millimeter wave systems that require automatic attenuation adjustment. The attenuator covers a frequency range of 75 to 110 GHz. Attenuation bias and control can accommodate remote operation from 0 to 35 dB through a 4-pin male connector. The attenuation step is 5 dB. The control and interface circuits of the actuator have been customized and uniquely packaged within the attenuator housing. Microprocessor based electronic devices improve the speed of precision actuators to ensure fast and accurate positioning. The input and output port configuration provides an inline structure with WR 10 waveguide and UG-387/U-M anti warping flange.
