Piezoelectric SAW BPF
(1000 to 2500 MHz)
F6 Series (L2 type)
s
DESCRIPTION
The F6 series of SAW band pass filters apply to the frequency range 1000 to 2500 MHz.
The SAW filters are fabricated on a lithium tantalate (LiTaO
3
) substrate, producing filters with a wide frequency
bandwidth, low insertion loss in passband and superior stability due to the high electromechanical coupling
coefficient of the material.
Fujitsu’s leading techniques for making filter pattern designs realized this high frequency filter.
The F6 series filters are housed in a small surface mount package. Moreover, the impedance in the passband is
50
Ω,
and so applications require no external matching circuits.
The F6 series SAW filters are suitable for interstage RF filter in mobile communications systems in the sub
microwave frequency band. Standard devices are available for PCS, DCS1800, and 2.4 GHz wireless LAN
systems.

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.
