MPX 2/6

6-Resonator Mini-Duplexer for the 160 MHz band
Description
  • The MPX 2/6 is a 6-resonator miniaturized duplex filter for duplex transceivers. This compact “miniplexer” meets the demand for a modern space saving, high performance filter type.
  • Model MPX 2/6 L can be tuned within the band 138-156 MHz and model MPX 2/6 H within the band 152 – 175 MHz, both with duplex spacing between 4 and 15 MHz.
  • The MPX 2/6 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 several channels, i.e. within a certain port bandwidth. In the last case, factory tuning is recommended.
  • The miniaturization of the filter has been realized by using special high-Q, temperature compensated helical resonators with discrete-component interconnections.
  • The housing is made of extruded aluminium, and the connectors are provided with teflon insulation.
  • The filter is coated with black vinyl to prevent corrosion.
