Filter (SAW, Dielectric, Thin Film)Since SAW filters came into actual use in the middle of the 1970s as video intermediate frequency filters, research and development efforts have remained vigorous to enhance their operating frequencies and performance for use in mobile telecommunication equipment. As a result, SAW filters began to appear in cellular phones, cordless phones and pagers. These filters are applied in communication systems, radio transmission systems, GSM, UMTS, CDMA-applications, PCNapplications.SAW Resonators Resonators are used as narrow band filters or frequency determining elements in oscillators. Their direct generation of frequency in the UHF and lower-microwave range makes them suitable for designing particularly low-noise oscillators in radio- relay, satellite communications, radar applications and remote control systems. Dielectric Filters / Ceramic Pass Band Filters Antenna Duplexer Ultrasonic oscillation will be created by a ceramic pass band filter which generates a direct axial wave (as in the air) in the entire volume of the piezoelectric material. Dielectric filters are used in communication systems as PCN, PCS, DECT, wireless LAN, Bluetooth, DAB, SDARS, DTV CATV, TDMA, CDMA1900, DCS1800, ICO, GPS and 868 MHz for SRD.
