摘要: A reconfigurable bandpass filter with tunable bandwidth is demonstrated using a dual-mode microstrip square loop resonator. The switched between different perturbation arrangements two strategically placed pin diodes. This topology results in 2:1 passband ratio at 10 GHz. design made on Duroid, an organic material suitable for three dimensional (3D) integration the system-on-a-package (SOP) approach. reduced number of switches and compact characteristics achieved by this makes attractive component to be included RF modular systems multilayer
