Abstract
A method for synthesizing a two-section inductively-coupled lumped-element quadrature hybrid for broad-band applications is first proposed. Based on this analysis, a two-section inductively-coupled lumped-element quadrature hybrid operated at X-band is presented. The measured magnitude imbalance and phase difference are 2.4dB and 90°± 4° over the frequency band of 8-12GHz, respectively. Results show good agreement with the theoretical predictions.
