Research of a wideband frequency ac resistive divider

An ac resistive divider used in calibrating of wideband frequency power analyzer is developed in the paper. It also describes the design of the divider, and techniques to improve the performance of the divider, and reduce the ratio error and the phase shift. Testing results of the divider show that the long-term stability of ratio error is less than 10^-5, ratio error is less than10^-4, phase shift is less than 3mrad within 10 kHz.
