Filtro Activo Recursivo con Divisores de Potencia Metamaterial Asimétricos

Abstract

In this work, it is presented a recursive active filter implemented by means of unequal Wilkinson power dividers. These power combiners have been implemented by using metamaterial transmission lines based on complementary split ring resonators (CSRRs). The power dividers are designed in planar technology and thanks to the use of the metamaterial cells their dimensions have been reduced. Additionally, the designed recursive active filter presents a high gain and low noise at the same time that minimizes the number of employed lumped elements
