EWDM-8G18G-65-70MV

PMI Model No. EWDM-8G18G-65-70MV is a CW immune EW detector module operating over the 8.0 to 18.0 GHz frequency range. This model features an internal switch used to switch between the Bit IN and RF IN with input blanking on both ports. In addition, an RF output port is provided with a gain of 33 dB minimum. The video output is designed to drive a 150 ft. cable.
