CHC16U
Broadband 82 and 135-Channel
Range 54-550MHz (CATV 2-78,
95-99) and 54-860 MHz (CATV 2-135)
Accommodates any combination of
16 digital and/or analog signal inputs
for maximum system flexibility
Adjustable hybrid push-pull
amplifier compensates for losses
associated with passive combining
networks thereby improving carrierto-noise and harmonic distortion
Accommodates modulators and
processors with lower outputs,
thereby reducing costs for additional
signal conditioning
Directional coupler design and low
insertion loss provide improved
carrier-to-noise, system performance
and picture quality
High -30dB port-to-port isolation
provides spurious carrier protection
and minimizes undesired channel
interaction, reducing picture
distortion
-30 dB test port provides convenient
access for headend testing and system monitoring
Auxiliary AC outlet for convenience
The Pico Macom CHC16U Series are professional re-broadcast grade quality
high-isolation 16-channel active headend combiners available in 82-Channel
(54-550 MHz) and 135-Channel (54-860 MHz) frequency bandwidths.These
units are designed to combine up to 16 input channels into a common broadband output.The CHC16U Series features a front-panel-adjustable hybrid
push-pull amplifier to compensate for the combiner’s insertion losses and drive
the cable system directly.The high quality directional coupler design provides
high isolation between input ports, ensuring minimal interaction between the digital and/or analog input sources. Additionally, the units’high isolation and built-in
gain maximize carrier-to-noise ratio and overall picture quality. Pico Macom
backs up these products with its industry leading 5-year limited warranty.
