10.7MHz SERIES MCF
Differs from general crystal filters, these do not require a
transformer so it can be made extremely compact and
light. It also possesses excellent characteristics with the
high Q of quartz crystals. This crystal filter is suitable
principally for portable stations.
■ Features
8 Compactness and light weight
8 Stable temperature characteristics.
8 Outstanding vibration and shock resistant characteris-
tics.
