BPBR 4/66-HX-150

12-cavity Mobile or Base Station Pass-reject Filter for the

68 - 108 MHz band

DESCRIPTION

This type of filter uses 12 large 40 x 40 mm cavities all with 3.5 mm

silverplated helical resonators, diameter 19 mm.

Using these large helicals and cavities means higher Q-value and

possibility of using very small spacing between pass and reject.

Using large helicals and cavities also means higher power handling - up

to 70 W with 1.5 dB insertion loss and 100 W with 1 dB insertion loss.

BPBR 4/66-HX-150 is divided into two sub-bands:

Pass 68 - 78 MHz or Pass 78 - 86.375 MHz. The reject is

in both cases 87.6 - 108 MHz. Other tuning ranges on demand.

The cavities are made of extruded aluminium, the chassis of passivated

steel. All coaxial cables are the semirigid-type and teflon is used in

connectors and cables.

The filter is coated with black vinyl to prevent corrosion.

Please specify pass and reject frequencies when ordering.
