VOLTAGE TUNING OF MICROWAVE MAGNETIC DEVICES USING MAGNETOELECTRIC TRANSDUCERS

摘要

Tunable microwave magnetic devices that provide increased performance with reduced size, weight, and cost. The disclosed microwave magnetic devices are voltage-tunable devices that include ferrite substrates. To tune the devices, the magnetic permeability of the respective ferrite substrates is varied by external, voltage-tuned, magnetic fringe fields created by one or more magnetoelectric (ME) transducers.

主权项

1. A tunable microwave magnetic device, comprising:
a ferrite substrate; a micro-strip circuit formed on the ferrite substrate; and at least one magnetoelectric (ME) transducer, wherein the ME transducer is operative, in response to a voltage applied across the ME transducer, to create an external magnetic fringe field emanating from the ME transducer, the external magnetic fringe field effectively penetrating the ferrite substrate for tuning the microwave magnetic device.
