Abstract:
|
In order to obtain high-power handling, dual-mode patch HTS filters have been analyzed through Green's function and desegmentation techniques. A precise circuit model has been obtained and applied to the filter design process, and useful design curves relating filter parameters and physical dimensions of the square patch have been plotted. Several designs have been made using them and then optimized with the Method of Moments in the Spectral Domain. For higher order circuits, staggered coupled-line HTS filters have been considered. The designs have been made using the method of moments to compute the coupling capacitances, and then optimized with the Method of Moments in the Spectral Domain. One dual-mode patch filter and one staggered coupled-line filter have been fabricated on a YBCO film. Measurements agree well with simulations |
