This paper describes the design of a balanced signal distribution system to feed an n by n set of mixers with local oscillator signals equal in frequency, phase and magnitude. This system is used in a planar n by n receiving/ transmitting array that measures and/or controls the direction of arrival of the received/transmitted signals. The design steps are clearly described. Optimization goals and variables are specified and the results of linear, electromagnetic and combined simulations are

This paper is a typical example of a successful computer-aided design which saves time, effort and money before manufacturing a prototype. It introduces the active power divider as a zero-loss signal distribution device.
