TYPICAL RESPONSE CURVES
The LPZ 1900 is used to prevent RFI (Radio Frequency Interference) caused
by excessive harmonic generation from transmitters operating in the 1900
MHz band. By rejection, the filter reduces the amplitude of the harmonics
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.
