Procom DPF 8-6-hx-150 - Manual

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.
