Observing limitations of the discrete Hilbert transform with S-parameter measurements of microstrips and striplines
S-parameter measurements of microstrips and striplines were done. The physical properties of the devices under test, consisting of nine single coplanar traces and nine pairs of coupled coplanar traces, are provided. The lab setup and equipment used to make such measurements are explained along with …

Multi-connection vias for printed circuit boards
… of in-plane circuit board features, such as striplines, microstrips and co-planar waveguides are tuned to control signal impedance. Conventional multi-layer vertical interconnects, which connect between board layers, are not impedance matched to the in-plane signal traces. Multi-connection …
