CEF/750
Single-Channel Elimination Filter
CEF750 125-Channel Passband 54-
750 MHz (CATV 2-125) eliminating
any single channel between 54-
456MHz (CATV 2-62)
Deep -55dB typical cavity-tuned
notch filter for clean signal removal
of selected cable channels and
subsequent insertion of locally
originated signals
High-Q helical resonators with
unique coupling circuitry provide
excellent long-term stability
Sharp filter cut-off edges allow
adjacent channels to be processed
with negligible loss
Up to 4 units can be cascaded for
multiple channel elimination
and reinsertion with negligible
interaction
Compact and efficient design
enables single rack unit (1
height installation saving valuable
rack space
Failsafe installation as input and
output may be reversed without
effect

CEF/750
Single-Channel Elimination Filter
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
4
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.
