Modern Coaxial Microwave Power Calibrators in the Frequency Band Up To 50 GHz

Measurement Techniques Aims and scope

Coaxial power calibrators and ways of improving them for checking terminal-type wattmeters are considered. Measurement of the complex effective reflection coefficient \( {\dot{\Gamma}}_{\mathrm{eff}} \) of the output of the calibrators enables the Γ-correction method to be used when transmitting the unit of power by the direct comparison microwave method, which considerably reduces the mismatch error. The errors in measuring \( {\dot{\Gamma}}_{\mathrm{eff}} \) are analyzed and the results of measurements by different methods are compared. An automated system for checking wattmeters using Γ-correction is described.
