ASSP Mobile Communication Systems
Piezoelectric SAW BPF (700 to 1000MHz)
F5CH Series (L2 Type)
DESCRIPTION
The F5CH series of SAW bandpass filters apply to the frequency range 700-1000MHz. 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. The F5CH series filters are housed in a small surface nount package. Moreover, the
impedance in the passband is 50 ohms, and so applications require no external matching circuits.
The F5CH series SAW filters are suitable for interstage RF filtering in mobile communications systems in the frequency range 700-
1000MHz. Standard devices are available for AMPS, ETACS, GSM, EGSM, PDC and so on.
FEATURES
• Low insertion loss and high attenuation
• High handling power ( 0.2 Watt)
• Ultra compact and light package (3.8mm )
• External matching circuits are not required
• Surface mount package (SMT)
• Wide variety of standard devices for worldwide mobile communication systems (AMPS, GSM, EGSM, ETACS, PDC800, NTACS, 2
Way Pager, etc.)
