Abstract

The first experimental results on a nondispersive, bandwidth tunable magnetostatic wave (MSW) filter using the forward and backward volume wave (BW) propagation at X-band are shown and compared with theoretical predictions. In order to build up a configuration as simple as possible including just two coupled filters, two delay lines with opposite frequency behavior have been utilized. By using this solution, the possibility for tuning BW up to 400 MHz is achieved. It is concluded that the MSW filter configuration considered is suitable for BW tunable, nondispersive device applications. However, the filter needs improvements to optimize the band shape, especially to steepen the low-frequency side and to minimize the ripple amplitude
