Band Pass Filters BPF 70/4.
Band-Pass Filter for the 450 MHz Band.
The BPF 70/4 is a 4 resonator ¼ λ 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 at the output of a transmitter, the BPF 70/4 reduces spurious signals.
The BPF 70/4 is adjustable over the range 380 - 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 70/4 is coated with black vinyl to prevent corrosion.
The filter is delivered in standard version with 4 MHz bandwidth, other bandwidths can be requested when ordering (up to 10 MHz)
