B170 SAW filters

Epcos has developed a series of SAW filters for digital satellite radio systems and receivers for home, vehicle and portable use.

Digital satellite radio is one of the most dynamic consumer electronics markets. Compared to other multimedia applications, digital satellite radio receivers and equipment require several different IF SAW filters due to the diverse terrestrial and satellite paths. The B170 series of IF bandpass filters in a ceramic SMD package are designed for low insertion attenuation. In the stopband, attenuation rates up to and exceeding 50dB are attained. Other filter series employed for digital satellite radio systems include the X730 series in a plastic case, and the B171 series in a ceramic SMD package. All of the packages developed were designed to suit applications in both consumer and automotive electronics environments.
