MSW Reflecting Array Filters,
Abstract
Surface Acoustic Wave (SAW) Reflective array filters (RAF's) which operate very effectively in the VHF/UHF range experience significant technical difficulties as the operating frequency is increased above 1 GHz and bandwidths greater than 300 MHz are required. In particular, operation above 3 GHz requires submicron device dimensions and corresponding propagation loss is high. Recently, it has been proposed and demonstrated that quasi-isotropic magnetostatic forward volume waves (MSFVW) propagating in liquid phase epitaxially grown. YIG films can be obliquely reflected by arrays similar to those used in SAW RAF's to provide bias field tunable, compact, nonrecursive transversal filter at microwave frequencies (1-20 GHz). This paper will describe the background and status of this new RAF technology based on MSFVW propagation in low linewidth thin film YIG. The propagation of MSFVW is nominally isotropic in the plane of the film, with a lowest order mode bandwidth of greater than 2 GHz with center frequency bias field tunable.
