Procom BPBR 4-66-hx-150 - Manual

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.
