Model: EWDM-2G6G-65-70MV
    

 

PMI Model No. EWDM-2G6G-65-70MV is a CW immune EW detector module operating over the 2.0 to 6.0 GHz frequency range. This module features an internal switch used to switch between the "Bit In" and RF In" with input blanking on both ports. In addition, two amplified RF outputs are provided a 7 dB gain channel and a 33 dB gain channel. The video output is designed to drive a 150 ft. cable, while maintaining high speed, and excellent accuracy.
