Duplex FiltersDPF 1400/6

6-Cavity Duplexer for 1400 MHz Band

Description

  • The DPF 1400/6 is a 6-cavity duplex filter.
  • The DPF 1400/6 can be tuned within the 1240 - 1600 MHz band with a nominal duplex separation of 35 MHz.
  • The filter uses full-length ¼ λ cavities in a compact, extruded aluminium housing. The chassis is made 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.
