TFS420K [Microchip]

Surface Acoustic Wave (SAW) devices are compact, cost competitive radio frequency (RF) solutions that can be used in a wide range of applications from VHF-band to S-band frequencies. Such microwave acoustic devices utilize conversion between electromagnetic and mechanical energy by use of the piezoelectric effect, which facilitates miniature filter solutions in modern electronic systems. The major advantages of the SAW filters are their potential for low insertion attenuation and excellent shape factor, small size, high reliability and temperature stability, as well as easy availability of custom designs. Surface Acoustic Wave (SAW) devices can be realized as bandpass and bandstop filter solutions, delay lines and resonators. In addition, we provide high performance signal processing solutions such as switched filter banks, passive SAW multiplexers and pulse expansion compression filters.
