3278 UHF bandpass filters are available in two, three
or four cavity models to provide three different configurations
that are increasingly selective. They are used for UHF processor
cleanup or for pre-amp protection against overload from strong
off air interference. They are factory tuned to a specified channel,
but can be factory retuned to any channel from 450 to 890 MHz.

3634 Custom &
3634FM Series Filters
Model
3634 custom filters utilize three helical resonators
for extremely high Q. This minimizes the insertion loss for narrow
bandwidth applications and results in high selectivity.
The
Model 3634FM can be tuned to any FM receive channel from
88 to 108 MHz by means of three self-locking screwdriver adjustments.
This filter is used for isolating a desired FM channel in the
presence of strong interference from undesired signals. It can
be shipped factory tuned to the customer's specified frequency. |
