Monolithic crystal filters (MCF) 21.4 MHz
International Crystal Manufacturing (ICM) offers a wide selection of
21.4 MHz monolithic crystal filters for use in wireless and telecommunications
applications. ICM 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.
