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.
