LPZ 1300

Coaxial Low-Pass Filter for the 1300 MHz Band

  • Passes all signals in or below the 1100 - 1300 MHz band.
  • Rejects signals above this range.

DESCRIPTION

  • Absolute stop band from 2.5 GHz to 12.4 GHz
    - no degradation at harmonics (Zolotarev-characteristic).
  • Attenuation in stop band better than 60 dB.
  • Insertion loss in pass range less than 0.4 dB.
  • Provided with brackets for panel mounting.

MOUNTING DETAILS

The LPZ 1300 is used to prevent RFI (Radio Frequency Interference) caused by excessive harmonic generation from transmitters operating in the 1100 - 1300 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.
