摘要：

Tapped delay lines are an attractive implementation for superconducting microwave filters because a wide range of phase and amplitude characteristics can be produced with single layer patterning (plus ground planes), while long delay lines do not introduce large additional loss. A numerical synthesis procedure for low-loss surface acoustic wave devices has been adapted for microwave filters. Multiple reflections and energy depletion are allowed for, permitting relatively large amounts of energy to be drawn by the taps. The procedure is demonstrated for linear phase filters, complementing work on chirps published elsewhere. The device is probably the first linear phase superconducting filter of any kind.
