MONOLITHIC CRYSTAL FILTERS

ELECTRICAL CHARACTERISTICS (10.7 and 21.4 MHz)

For 12.5 KHz Channel Spacing (Operating Temperature -20 to +70˚C)

ECS’s Monolithic Crystal Filters have very
high Q’s and excellent temperature and
aging characteristics. These 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 four, six and
eight (or more) pole filter responses.

FEATURES

•

High stability for wide temperature ranges
