The Pico Macom CEF750 is a professional grade single channel elimination fil-
ter 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 origi-
nated 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 mini-
mum 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 CEF750 is 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.
