Scope
This specification shall cover the characteristics of the XT…MB Ceramic Filter.
Ceramic Filters LTM 455/450W Series are miniaturized versions of
the CFU/CFWS lines. These compact, highly selective
characteristics are recommended for use in applications ranging
from two-way radio to auxiliary filters in high class
transceivers.These ultra-miniature versions consume approximately
40% less volume while still offering the same high performance
characteristics.
