Custom crystal filters, overview of capability. BAND PASS FILTERS Narrow Band Pass Crystal Filters Narrow band pass crystal filters are designed to pass a narrow frequency band and reject all other frequencies. The maximum band width using fundamental mode crystals is 0.3% of the centre frequency and is 0.03% when using third overtone crystals. Frequency range 1.0MHz to 100.0MHz. Intermediate Band Pass Crystal Filters The maximum bandwidth of this range of crystal filters is 2.0% of the centre frequency. Frequency range 1.0MHz to 100.0MHz. Linear Phase Crystal Filters To avoid distortion and ringing due to group delay it is necessary to have a flat time-delay characteristic. The group delay of a highly selective filter, varies considerably within the pass band. This introduces distortion into digital and low noise transmission signals. These problems can be overcome by specifying a Linear phase crystal filter. Frequency range 1.0MHz to 180.0MHz. SPECIALIST CRYSTAL FILTERS Comb Filter Banks A comb filter bank is made up of a number of crystal filter elements which are used to divide a particular frequency spectrum into discrete elements. Frequency range 1.0MHz to 100.0MHz. Band Reject Filter A band reject filter is a narrow band device which will reject a single frequency from a spectrum of frequencies
