Filtros dúplexDPF 2/44

8-Cavity Duplexer for the 160 MHz Band

Descripción

  • The DPF 2/44… is a 8-cavity duplex filter for duplex radio transceivers.
  • This duplexer is delivered in a low band version type DPF 2/44 L, tunable within 138 - 156 MHz and a high band version type DPF 2/44 H, tunable within 152 - 175 MHz. These models are again delivered in 3 submodels, each dedicated to work with a certain duplex spacing. See  Ordering information under the "Specifications" tab below.
  • The DPF 2/44… models are primarily intended for equipment, where the Tx and Rx operate on several channels, (multi-channel turned) i.e. within a certain port bandwidth.
  • The filter has very small physical dimensions owing to the use of high-Q, temperature compensated helical resonators.
  • The housing is made of extruded aluminium, the chassis of passivated steel, and teflon insulation has been applied in the rigid coaxial cables and in the connectors.
  • The filter is coated with black vinyl to prevent corrosion.

Ordering Information

When ordering, please use the table above to select the appropriate ordering designation for the desired filter type. 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.

Special configurations of this filter type may be quoted on request. For instance, the filter can be delivered with other connector types or with flying leads (RG 316 coaxial cable) terminated with connectors or for soldering-connection.
