Dual Six-Port Reflectometer Systems Using Waveguide in the Frequency Range 18-50 GHz

Abstract

The development and evaluation of three dual six-port reflectometer systems, that use WR-42, WR-28 and WR-22 waveguide, is discussed; these cover the frequency range 18-50 GHz. automated operation and will provide complex scattering parameter data for customer waveguide components, as well as effective efficiency data for power sensors. Some representative measurement data are presented that demonstrate that these systems yield results that do not differ significantly from those obtained using older measurement systems. Some discussion of measurement uncertainties is also included.
