TIMING EXTRACTION FILTER
(50 to 300MHz)
F4 SERIES
s
DESCRIPTION
The F4 series are timing extraction filter used in the high-grade digital transmission equipment like wide-band
ISDN. The F4 series uses a single lithium tantalate piezoelectric crystal (L

) that has large electromechanical
coupling coefficient, and a unique SAW resonator. That provides wide bandwidths, insertion loss, and
exceptional stability in VHF band until 300MHz.
