Monolithic Crystal Filter ECSs Monolithic Crystal Filters have very high Qs and excellent temperature and aging characteristics. These filters offer narrow and intermediate bandwidths. The Request a Sample monolithic crystal filter is smaller and more cost effective than a discrete crystal filter. With the addition of coupling capacitors between two-pole sections. They can be cascaded to produce four, six, and eight (or more) pole filter responses.
