Band Pass Filters BPF 900/3.

Band-Pass Filter for the 900 MHz Band.

The BPF 900/3 is a 3-cavity band-pass filter using full-length quarter-wave resonators.

This filter can be used as a preselector to protect a receiver against interference from transmissions out of the passband, or it can be used to reduce spurious output from a transmitter with up to 50 W output power.

The filter can be tuned within the entire 820 - 960 MHz band. Careful design and choice of materials ensure reliable operation over a wide temperature range.

The housing is made of extruded aluminium, the chassis of steel, and teflon insulation has been used in the coaxial cables and in the connectors.

BPF 900/3 is coated with black vinyl to prevent corrosion.
