The Pico Macom MCM55 is a high quality hybrid push-pull wall-mounted
distribution amplifier producing signals with extremely low-noise and har-
monic distortion.These amplifiers are capable of 42 channel operation over
the 54-300MHz range in smaller MDU, CATV or SMATV systems. Because of
its high gain and low noise figure, the MCM55 is also ideally suited for head-
end applications with low-level input signals.The hybrid module provides
excellent heat sinking capabilities that are required for the reliability of a high
output amplifier.To ensure reliability and minimize heat build-up within the
unit, an external UL approved power adapter is supplied.
