The Pico Macom CEF550 and CEF750 are professional grade single channel elimination filters designed to provide a 6MHz-wide carrier-free environment to insert locally originated channels. When used in conjunction with Pico Macom’s high quality modulators, these units are the most cost-effective method to add locally originated programming to an MATV or CATV system while ensuring the highest quality picture across the band. This unit employs multi-stage cavity bandpass and notch filtering to provide single channel rejection depth typically greater than -55dB, thereby eliminating disruptive carriers and greatly improving picture quality. Also, the unique filter design and sharp frequency cut-off provide minimum adjacent channel disruption and excellent passband frequency response ensuring no degradation in system performance. In systems requiring more than one inserted channel, up to 4 units can be cascaded for multiple channel elimination and reinsertion with negligible interaction. The CEF550 and CEF750 are pre-tuned to any channel in the notch range for easy drop-in installation. Pico Macom backs up this product with its industry leading 5-year limited warranty.
