Mobile Communication Systems
Piezoelectric SAW BPF
(700 MHz to 1000 MHz)
F5CM Series (B2)

DESCRIPTION
The F5CM series of SAW filters have balanced in/unbalanced out or unbalanced in/balanced out of I/O ports.
Therefore these filters are suitable for the design using balanced type of IC. By using these filters, any transforming
devises, such as balun is not required.
The F5CM series filters apply to the frequency range 700 MHz to 1000 MHz. High performance has been realized
with high reliability and small size by using original materials and original design.
The F5CM series filters are suitable for RF interstage filter in mobile communication systems and standard parts
are available for GSM and AMPS/TDMA/CDMA standards.

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 this range.
Always use piezoelectric devices within their recommended operating conditionranges. 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.
