ceramic filters lt10.7 series
lt10.7 seriesare monolithic devices which utilize the energy-trapped thickness vibration-mode.
this principle of operation is based upon the fact that an excellent resonating element with low spurious vibration can be obtained by adhering to certain theoretical parameters of design.
these parameters include the physical dimensions of the ceramic element, the electrode pattern, and the associated mass loading effect of the electrodes.
in addition to employing the principle of energy-trapped thickness shear vibration-mode, token also utilizes the theory of the multicoupling mode.
in short, this theory utilizes divided electrodes to "trap" different frequencies simultaneously.
the advantages of token's multicoupling mode technology is a highly selective, integrated device that allows a single piezo substrate to contain a number of coupled resonators.
token categorizes the lt 10.7 family according to rank of center frequency.
this ranking indicates that a given lt 10.7 will be marked with one of the colors listed in the following chart and will exhibit the center frequency characteristics specified below.
- frequency range: 10.7mhz.
- lt10.7m series for fm receiver compatible to murata sfe10m7 fm-if series.
- lt10.7m a10 series low-loss type compatible to murata sfe10m7 a10 series.
- lt10.7m wide/narrow band-width series compatible to murata sfe10m7 dbs receiver.
