Abstract

A YIG component for providing a microwave frequency output signal has a cavity holding an electromagnetic circuit defining an air gap between a pair of pole pins. The cavity having a tuning coil for generating a homogeneous magnetic field in the air gap, and further holding a YIG unit comprising a carrier; at least one ferrite crystal arranged in the air gap; and an interface connected to the ferrite crystal or crystals for providing the microwave frequency output signal. A magnetic core is included in the electromagnetic circuit and comprises the pole pins combined with magnetic flux closing path elements shaped as bars, the pole pins and the bar-shaped elements forming an open structure. The YIG component includes a support housing made of a nonmagnetic material having formed therein the above-mentioned cavity and having inside the cavity integral precision-tooled surfaces for the carrying and relative positioning of the electromagnetic circuit and the YIG unit. The surfaces comprise a first positioning seat for the magnetic core and a second positioning seat for the carrier, the core and the carrier being thus supported separately by the support housing.
