  • The version MPX 70/44 380-EXT is a 8-resonator small size Duplex Filter. It is especially developed for duplexing into one antenna the Tetra Public Safety extended band together with e.g. the Public Safety DMO (Direct MOde) frequency range 406 – 410 MHz, or together with the private Tetra networks e.g. in the freq. range 415 – 430 MHz.
  • This compact “miniplexer” meets the demand for a modern, space saving, high performance filter.
  • Overall the duplexer MPX 70/44 is available in a variety of different versions depending on duplex spacing, frequency, bandwidth and attenuation. Please ask Customer Service for availability.
  • The MPX 70/44 models are tunable within the frequency range 380 – 470 MHz The miniaturization of the filter has been realized by using special high-Q, temperature compensated helical resonators.
  • The housing is made of extruded aluminium, the chassis of steel, and teflon insulation has been applied in the rigid coaxial cables and in the connectors.
  • MPX 70/44 380-EXT is coated with black vinyl to prevent corrosion.
