BPF 70/6

Band-Pass Filter for the 450 MHz Band

PRELIMINARY DATA SHEET

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.

The filter is black vinyl coated to prevent corrosion.
