DPF 70/6-XL...
6-Cavity Duplexer for the 400 MHz Band
DESCRIPTION
The DPF 70/6-XL… is a 6-cavity duplex filter for duplex radiotelephones.
The DPF 70/6-XL… can be adjusted within the complete
340 - 400 MHz band. The duplexer can be supplied in four different
versions according to duplex spacing required.
See also “Ordering information” below.
The DPF 70/6-XL… is primarily intended for equipment with TX and RX
operating 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 last case, factory
tuning is recommended.
The filter uses full-length ¼ 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 black vinyl coated to prevent corrosion.
