DPF 8/6-HX-150

6-Resonator Duplexer for the 8 m Band

DESCRIPTION

  • The DPF 8/6-HX-150 is a six-cavity high-power mobile or base station duplexer for the 30 - 45 MHz band.
  • This type of filter uses six large 40 x 40 mm cavities, all equipped with 3.5 mm
    silver-plated helical resonators, 19 mm diameter.
  • The use of large cavities and resonators means higher Q, resulting in smaller duplex spacing with lower loss.
  • The larger dimensions extend power rating to 100 W continuous.
  • The DPF 8/6-HX-150 is designed for single-channel equipment, but can, with slightly reduced data, be broadband-adjusted to allow multichannel equipment to be used.
  • The cavities are made of extruded aluminium, the chassis of passivated steel. All coaxial cables are of the semi-rigid type, and teflon has been used in all connectors and cables.
  • The filter is black vinyl coated to prevent corrosion.
  • Please specify the frequencies for TX and RX when ordering, as all filters are made individually.
