Typical Response Curves
BPF 70/6
Band-Pass Filter for the 450 MHz Band
Description
- The BPF 70/6 is a 6-¼ λ resonator band-pass filter with inductive coupling between the resonators.
- This filter can be used as a preselector to protect a receiver from interference from transmitters outside the band-pass limits.
- When installed in the output of a transmitter, the BPF 70/6 reduces spurious signals.
- The BPF 70/6 is adjustable over the range 406 – 470 MHz.
- Careful choice of materials ensures reliable functioning over a wide temperature range.
- Extruded aluminium sections, steel racks and coax cables and connectors with teflon insulation ensure good mechanical strength.
- BPF 70/6 is coated with black vinyl to prevent corrosion.
