  • The BPF 900/3 is a 3-cavity band-pass filter using full-length quarter-wave resonators.
  • This filter can be used as a preselector to protect a receiver against interference from transmissions out of the passband, or it can be used to reduce spurious output from a transmitter with up to 50 W output power.
  • The filter can be tuned within the entire 820 – 960 MHz band. Careful design and choice of materials ensure reliable operation over a wide temperature range.
  • The housing is made of extruded aluminium, the chassis of steel, and teflon insulation has been used in the coaxial cables and in the connectors.
  • BPF 900/3 is coated with black vinyl to prevent corrosion.
