BPF 8/3
Band-Pass Filter for the 8 m Band
Description
- This filter can be used as a preselector to protect a receiver against interference from transmissions out of the pass-band, or it can be used to reduce spurious output from a transmitter with up to 50 watt of output power.
- The BPF 8/3 is a 3-helical resonator band-pass filter with aperture-coupling between the resonators.
- The filter 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 passivated steel, and teflon insulation has been used in the coaxial cables and in the connectors.
- The filter is black vinyl coated to prevent corrosion.
- Band-pass filters similar to the BPF 8/3 but with pass-band frequency between 30 and 66 MHz may be quoted on request.
