Fox filters offer excellent features such as sharp cut off characteristics,
low loss and high stability over a wide temperature range which are
superior to LC Filters and Ceramic Filters.
The basic building block for all custom built Fox filters is the two-
pole monolithic filter available in standard package as shown. Two-
pole monolithic filters are cascaded to produce four, six and eight
pole filter responses with the addition of coupling capacitors
between two-pole sections. Standard Fox filters are available with
center frequencies from 10.7 MHz to 90 MHz, and from two to
eight poles.
For custom made filters, please specify the following:
Holder Size
Nominal Frequency
Pass Bandwidth
Note: 45F Series 45.000 MHz fundamental is a special filter designed for mobile
radio and cellular phone applications.
