  • The BPF 2/3 is a 3-helical resonator band-pass filter with aperture-coupling between the 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 144 – 175 MHz band. It has very small dimensions owing to the use of helical resonators. 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.
  • The filter is black vinyl coated to prevent corrosion.
  • Please specify frequency when ordering
