Miniaturized broadband multisection coupled-line wilkinson power divider designed with the use of quasi-lumped element technique

The design of a miniaturized broadband Wilkinson power divider has been presented. To achieve broadband frequency response a three-section coupled-line structure has been used. All coupled-line sections have been realized with the use of a quasi-lumped-element approach, which allowed for significant miniaturization of the resulting network. Each coupled-line section has been designed with the use of a three-section equivalent circuit for which analytical expressions describing the required values of the lumped elements are given.
