A new analysis of nway hybrid power dividers with arbitrary power splitting ratios
Abstract
An analysis is carried out of nway Hybrid Power Dividers (HPD) which split an input signal into n output signals in phase and with arbitrary amplitude ratios, and which is obtained by cascading M sections of coupled nwire lines of equal length with isolation resistors that are given by a general nport resistive circuit including the Yconnection. It has been described that n output port conductances, characteristic admittance matrices and isolation resistors are directly obtained from the power dividing ratios. The analysis is done by getting the eigenvalues and the corresponding eigenvectors of characteristic admittance matrices of nwire coupled lines and admittance matrices for isolation resistors multiplied by the diagonal matrix constituted with the power dividing ratios. By this analysis, it has been shown that the (n+1)port made with a coupled nwire line with isolation resistors of the Yconnection acts as an nway HPD at narrowband frequencies. The broadband nway HPD may be obtained easily by numerical computation, because the scattering matrix of an nway HPD has been obtained.
