Abstract

A computational method of unbalanced single-input two-output (1:2) interconnect with coupled interbranch is introduced. The circuit theory is built with the topology constituted by the octopole Z-matrix represented by the coupled lines. The voltage transfer functions (VTFs) and the input impedance of the input-output electrical path of the unbalanced 1:2 tree with interbranch coupled lines are established. The computation model is verified with proofs of concept (POC) constituted by unbalanced 1:2 tree microstrip structure with and without interbranch coupled phenomenon. The POCs are loaded by resistors and capacitors. Good agreements between the simulated and modelled VTFs and the overall structure input impedances were obtained from 0.1-to-2 GHz.
