MONOLITHIC CRYSTAL FILTERS 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 Insertion Loss Ripple Nominal Frequency Attenuation Terminating Impedance Pass Bandwidth Spurious Response Operating Temp. Range Note: 45F Series 45.000 MHz fundamental is a special filter designed for mobile radio and cellular phone applications.
