TYPICAL RESPONSE CURVES
PLEASE NOTE
The LPC 470 is used to prevent RFI (Radio Frequency Interference) caused
by harmonics and spurious signals from transmitters operating in the 450
MHz band. By rejection, the filter reduces the amplitude of the various
spurious signals and prevents them from being radiated by the antenna.
The filter is normally used in connection with base station transmitters, but
as it is mechanically very ruggedly designed, it is perfectly suited for mobile
and marine applications as well.
