DPF 8/6-4/8
6-Resonator Duplexer for the 8 m Band
Description
- The DPF 8/6-4/8 is a 6-resonator duplex filter for duplex radiotelephones.
- The filter is primarily intended for equipment where the Tx and the Rx operate 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 can be tuned within the 34 – 42 MHz band with a duplex separation between 4 and 8 MHz.
- The filter has very small dimensions due to the use of high-Q, temperature compensated helical resonators with discrete-component interconnections.
- The housing is made of extruded aluminium, the chassis of passivated steel, and the connectors are provided with teflon insulation.
- DPF 8/6-4/8 is coated with black vinyl to prevent corrosion.
