Abstract :
In this paper, we describe a new dual signal probe, and vector network analyzer (VNA) calibration standards providing high isolation between signals. Previously existing probes and standards may exhibit high coupling, making them unsuitable for use with conventional VNAs. The new design significantly reduces the signal-to-signal coupling of the probes and standards, enabling improved calibration and measurement to beyond 40 GHz.
