wideband FM systems. It is intended for use with an IF input
frequency from 300MHz to 700MHz in satellite receivers. It
consists of an input RF amplifier, signal level detector, UHF phase
detector UHF oscillator and video/loop amplifier. Both positive
and negative going video outputs are available.
