- Separates two frequencies to allow a single antenna to be used for transmitting and receiving signals at the same time. 6-cavity duplexer for the 450 MHz band
- DESCRIPTION
- 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. See also “Ordering information” below.
- 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
