Computer-aided design of a singly-matched (S-M) multiplexer with a common junction

Formulas based on scattering parameters are presented for the design of a multiplexer composed of n-1 channel equalizers connected either in parallel or in series at a common junction with a 1-Ω resistive generator and n-1 channel complex loads. It is shown as the singly-matched (S-M) multiplexer. A two-stage computer-aided design (CAD) approach is developed for the S-M multiplexer. A design example of a three-channel S-M multiplexer including the designs of three individual S-M channel equalizers is given to demonstrate the approach
