It makes the cost, performance, form factor, and power consumption of these systems, including cellular phones, critical issues. At present, the fixed frequency filter banks based on Film Bulk Acoustic Resonators (FBAR) are regarded as one of the most promising technologies to address performance -form factor-cost issues. Even though the FBARs improve the overall performances the complexity of these systems remains high. Attempts are being made to exclude some of the filters by bringing the digital signal processing (including channel selection) as close to the antennas as possible. However handling the increased interference levels is unrealistic for low-cost battery operated radios. Replacing fixed frequency filter banks by one tuneable filter is the most desired and widely considered scenario. As an example, development of the software based cognitive radios is largely hindered by the lack of adequate agile components, first of all tuneable filters. In this sense the electrically switchable and tuneable FB | | 出版日期 | Book 2013 | | 关键词 | Film Bulk Acoustic Resonators; Paraelectric Phase Ferroelectrics; Resonant Frequency; Tuneable FBARs | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4471-4944-6 | | isbn_softcover | 978-1-4471-5844-8 | | isbn_ebook | 978-1-4471-4944-6Series ISSN 1619-0181 Series E-ISSN 2365-0761 | | issn_series | 1619-0181 | | copyright | Springer-Verlag London 2013 |
