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.
