Single-Channel Elimination Filter
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 improv-
ing 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
4
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.
