DPF 70/6-5/7-N

Duplex Filters DPF 70/6.

6-cavity duplexer for the 450 MHz band.

The DPF 70/6… is a 6-cavity duplex filter for duplex transceivers.

The DPF 70/6… can be adjusted within the complete 406 - 470 MHz band. The duplexer can be delivered in four different versions according to required duplex spacing. 

The DPF 70/6… is primarily intended for equipment where the Tx and Rx operate on single frequencies, but it can also, however with slightly reduced data, be used where the Tx and Rx operate on multi channels, i.e. within a certain port bandwidth. In the last 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.

DPF 70/6... is coated with black vinyl to prevent corrosion.
