Abstract :
Magnetically tunable filters and oscillators can be built throughout the 500-MHz-110-GHz range using a number of ferrite materials and varied geometries. The authors survey current trends and state-of-the-art results for oscillators and filters using YIG spheres , YIG films, and hexagonal ferrites as the magnetically tunable elements
