Diseño, simulación e implementación de divisores de potencia de banda ancha para las bandas ISM

Abstract

Abstract: Power splitters are generally defined as a network of three or more ports that distribute an input signal to a number n of outputs. The main problem that these devices are their low bandwidth. This end of degree project describes the design, simulation and implementation of Wilkinson power dividers and broadband Branch line for the 2.437Ghz ISM band using microstrip technology and the FR-4 substrate. The design focuses on establishing the specifications and equations to be used for divisors of multi-stage power. With the optimized design, the ADS software version 2020 is used to perform the simulation of the Wilkinson and Branch line power dividers of one, two and three stages. The implementation is carried out through the machining method and its characterization through a network analyzer (VNA) equipment used to obtain data from the prototypes. The results obtained show that when increasing stages to a power divider your bandwidth grows exponentially.
