■DESCRIPTION

The F5CH series of SAW bandpass filters apply to the frequency range 700 to 1000 MHz. The SAW filters are fabricated on a lithium tantalate (LiTaO3) 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 mount 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 filter in mobile communications systems in the frequency range 700 to 1000 MHz. Standard devices are available for AMPS, ETACS, GSM, EGSM, PDC and so on.
