Abstract
A magnetically-tunable ferrimagnetic radio frequency (RF) circuit sub-assembly can include a resonant cavity comprising a first magnetically conductive member spaced apart from a second magnetically conductive member, and a side wall. The sub-assembly can include first and second ferrimagnetic elements arranged in spaced apart relation within the resonant cavity. The sub-assembly can include a transmission line comprising a first portion located for RF coupling to the first ferrimagnetic element and a second portion located for RF coupling to the second ferrimagnetic element.
