The equivalent source mismatch (GammaG) of a 1.85 mm coaxial power splitter was characterized by use of two statistical measurement techniques. The first technique, originally described by Juroshek uses a modified one-port calibration method to determine GammaG. The second method uses two-port measurements of the splitter with one of the ports loaded with a series of calibration standards. This second,...
We present a technique for accurate wideband measurements of one-port devices with extreme impedances. Our technique uses a reflectometer with variable parameters (states) to obtain redundant measurements of the extreme impedance device. We process these measurements using statistical techniques that allow us to exploit the redundancy in order to increase the measurement bandwidth and reduce the measurement...
We present a statistical technique for one-port vector network analyzer (VNA) calibration based on multiple reflect and a single reference standards. The multiple reflect standards are assumed to be partly unknown and of the same type, e.g. offset terminations. Their reflection coefficients are modeled over frequency and identified during the calibration along with the VNA error terms. This novel...
