Butler Matrix Based Six-port Passive Junction
Moscoso Mártir, Álvaro; Ávila Ruiz, Jose Manuel; Durán Valdeiglesias, Elena; Moreno-Pozas, Laureano
; Molina-Fernandez, Iñigo; Ortega-Moñux, Alejandro; De-Oliva-Rubio, Jose[et al.] (2014-02-03)
In this work we propose the utilization of the Butler matrix as a six-port I/Q demodulator. The inherent symmetry of its topology allows to overcome the intrinsic amplitude and phase imbalances of the traditional approaches ... -
Circuitos de Radiofrecuencia de Banda Ultra-Ancha en Tecnología Planar Integrada: Aplicación a Receptores de Seis Puertos
(Servicio de Publicaciones de l Universidad de Málaga, Servicio de Publicaciones, 2013)Se presenta el diseño, implementación y evaluación experimental de un demodulador I/Q de seis puertos analógico de altas prestaciones, capaz de operar en la banda de 3.1 a 10.6 GHz sin necesidad de técnicas de calibración. ... -
Discriminador de frecuencia basado en resonadores “dual-mode” sintonizables
In this paper a novel varactor-tuned frequency discriminator that makes use of two tunable dual-mode microstrip resonators is demonstrated. In this circuit, the two tuned modes of the resonators are used independently to ... -
Varactor-Tuned Dual-Mode Frequency Discriminator for Instantaneous Frequency Measurements
Moscoso Mártir, Álvaro; Molina-Fernandez, Iñigo; Hong, Jiasheng (IEEE European Microwave Week, 2013)
In this paper a novel varactor-tuned frequency discriminator that makes use of two tunable dual-mode microstrip resonators is demonstrated which doubles the discriminator tuning bandwidth. To prove its validity a prototype ...
