Abstract :
Wideband communication and radar systems require high-speed electronically tuned wideband microwave band-stop and band-pass filters. Ferromagnetic resonance (FMR)-based microwave devices possess the unique capability of high-speed electronic tunability, using magnetic field, for very high carrier frequency and very large bandwidth. In this paper, low-loss magnetically tuned wideband microwave band-stop and band-pass fillers using yttrium iron garnet/gadolinium gallium garnet-gallium arsenide (YIG/GGG-GaAs) layer structures are reported. Modeling arid simulation has been carried out for both types of filters using the lumped-element equivalent circuit model.
