Ordering Information
If duplex Tx and Rx frequencies are stated when ordering, the duplexers are delivered factory-adjusted. If Tx and Rx frequencies are not stated, the filters are delivered non-adjusted.
DPF 70/6-XL
6-cavity duplexer for the 350 MHz band
Description
- The DPF 70/6-XL is a 6-cavity duplex filter for duplex transceivers.
- 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.
Also see “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.
