Abstract :
Resistive dividers for wideband power analyzers have been designed. They have been built with identical resistors connected in series and parallel in a quasi-coaxial structure. Simulations on the PSpice models, the methods developed for their calibration and the preliminary experiments show that the accuracy for frequency up to 20 kHz can be better than 30 parts in 106 for the ratio and 20 μrad for the phase difference.
