EPCOS have developed a new series of SAW filters for digital satellite radio systems and receivers that are suitable for home, vehicle and portable use. The series of SAW filters for digital satellite radio systems are available from Ramelec Electronics . Other multimedia applications such as sets, digital satellite radio receivers and equipment require several different IF SAW filters because of the diverse terrestrial and satellite paths.
The new EPCOS B170 series of IF bandpass filters, which is in a ceramic SMD package is 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 series’ packages were designed to suit applications in both consumer and automotive electronics environments.
