DPF 2/55
10-Cavity Duplexer for the 160 MHz Band
Description
- The DPF 2/55… is a 10-cavity duplex filter for duplex radio transcivers.
- This duplexer is delivered in a low band version type DPF 2/55 L, tunable within 138 – 156 MHz and a high band version type DPF 2/55 H, tunable within 152 – 175 MHz. These models are again delivered in submodels, each dedicated to work with a certain Tx-Rx spacing. See “Ordering information” below.
- The DPF 2/55… models are primarily intended for equipment, 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 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 black vinyl-coated to prevent corrosion.
