Abstract:
Millimeter-wave six-port reflectometers for scattering parameter measurements in the WR-15 and WR-2.8 frequency bands have been designed and implemented. These reflectometers represent an effort to (1) develop a cost-effective measurement infrastructure that is scalable to terahertz frequencies and (2) to realize in-situ measurement instruments for monitoring the performance of millimeter-wave components. Performance of the six-ports has been assessed by applying them to measure the return loss for various components, including calibration standards and other common waveguide components. Measurement results have been found to be in close agreement with those obtained with a commercial HP8510C vector network analyzer. In addition, a WR-15 six-port reflectometer has been demonstrated as an in-situ sensor to monitor the mismatch between adjacent stages of a frequency multiplier chain.
