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)
