CEF
CEF550 89-Channel Passband 5-
550 MHz (CATV T7-T13 2-78, 95-99)
eliminating any single channel
between 54-216 MHz (CATV 2-13,
95-99)
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 (13/4˝)
height installation saving valuable
rack space
Failsafe installation as input and
output may be reversed without
effect
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
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.
