A magnetostatic-surface-wave linearly dispersive delay line with a 500 MHz bandwidth at 3 GHz and a phase error from quadratic of less than 13 degrees has been demonstrated. The device utilises a 3-layer propagation structure (YIG-dielectric ground plane) in which the spacing to ground plane varies along the propagation direction.
