Piezoelectric SAW BPF
(700 to 1000 MHz)
F5/F6 Series (K2 type)
s
DESCRIPTION
The F5CE/F6CE-K2 series of SAW band pass filters are available in the 700-1700 MHz frequency range and
exhibit high stability by using single crystal Lithium Tantalate (LiTaO
3
) with a large electro-mechanical coefficient.
The F5CE/F6CE-K2 series provides low insertion loss and wide passband width by taking advantage of Fujitsu’s
unique “Ladder-type” design.
The F5CE/F6CE-K2 series is housed in a small package (3.0 mm square) contributing to a significant savings in
mounting space. This package is 40 % smaller than our F5CH-L2 series (3.8 mm square). Typical applications
for the F5CE/F6CE-K2 series include RF interstage filtering in mobile communications systems. Standard devices
are available for AMPS/TDMA/CDMA,GSM, EGSM and various Japanese standards. If higher attenuation is
preferred, our F5CE-D2 series is also recommended.

WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
piezoelectric device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use piezoelectric devices within their recommended operating condition ranges.Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses , operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
