DPF UHF/33-DR 3000
6-Cavity Duplexer for the 450 MHz Band Repeater
DESCRIPTION
The DPF UHF/33-DR 3000 is a 6-cavity duplex filter designed to be built
into the Motorola DR 3000 duplex repeater.
The DPF UHF/33-DR 3000 can be adjusted within the complete
406 - 470 MHz band. The duplexer is delivered with a 10 MHz spacing.
The DPF UHF/33-DR 3000 is primarily intended for TX and RX operation
on single frequencies, but it can also, however with slightly reduced
data, be used where the TX and RX operate on several channels, i.e.
within a certain port bandwidth. In the latter case, factory tuning is
recommended.
The filter uses full-length ¼ λ cavities in a compact, extruded aluminium
housing. The chassis is made of passivated steel, and teflon insulation
has been applied in the coaxial cables and in the connectors.
The filter is coated with black vinyl to prevent corrosion.
