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.
