A Balanced Active Power Divider for Coherent Distribution of Local Oscillator Signal in a Planar Transmitting-Receiving Array

Abstract

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 given and compared. The final product layout is shown and its performance is described. 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.

Optimizing Radar Functionality: Development of a Steerable Patch Antenna Array with Enhanced Bandwidth

“…Our power divider, integral to the steerable array's architecture, was meticulously crafted following the principles outlined in reference [3]. The design facilitates uniform signal distribution to eight output ports, each spaced 30 mm apart, optimizing the array's spatial configuration for maximum performance.…”
