Monolithic Crystal Filters

ECS Monolithic Crystal Filters (MCF) have high Qs and excellent temperature and aging characteristics. ECS MCF filters offer narrow and intermediate bandwidths. The 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 4, 6, and 8 (or more) pole filter responses.
