DPF 2/6-HX-150
6-cavity Mobile or Base Station Duplexer for the 136 - 175 MHz Band
Description
- The DPF 2/6-HX-150 is a six-cavity high-power mobile or base station duplexer for the 136 – 175 MHz band.
- This type of filter uses six large 40 x 40 mm cavities, all equipped with 3.5 mm silver-plated helical resonators, diameter 19 mm.
- 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 2/6-HX-150 is designed for single-channel equipment, but can, with slightly reduced specification, 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.
