MCM integration and power amplifier matching of non-reciprocal devices

摘要

Devices are described herein that operate according to non-reciprocal behaviors. The devices may be manufactured and integrated into substrates and discrete components according to described techniques. The devices may be configured in ways to achieve increased device performance while decreasing the overall device size. The devices may be actively tuned to facilitate impedance matching with other circuit components such as power amplifiers. Tuning includes adjustment of magnetic fields and impedance values associated with the devices using techniques and components described herein and may be based upon changes in circuit or device parameters such as temperature, voltage, and current. The devices described herein may be configured as non-reciprocal devices that include ferrites with metallization patterns that may be in the form of microstrip circuitry or in stripline formats depending upon configuration.

1. A non-reciprocal device, comprising:
a ferrite core; a plurality of conductors magnetically operable with the ferrite core; a first plurality of vias through the ferrite core, each of the plurality of conductors electrically connected to one of the first plurality of vias; a substrate that includes a cavity, the cavity being coaxially aligned with the ferrite core; and a second plurality of vias in the substrate, wherein each of the plurality of conductors traverses a respective subset of the second plurality of vias.
