Filed:

Mar 14, 2008
Appl. No.:

12/049040
Inventors:

Alexander Khitun - Los Angeles CA,
Igor V. Roshchin - San Diego CA,
Kosmas Galatsis - Torrance CA,
Mingqiang Bao - Los Angeles CA,
Kang L. Wang - Santa Monica CA,
Assignee:

THE REGENTS OF THE UNIVERSITY OF CALIFORNIA - Oakland CA
International Classification:

H01Q 1/00
H03B 19/00
US Classification:

327113, 343787
Abstract:

A frequency conversion device, which may include a radiofrequency (RF) mixer device, includes a substrate and a ferromagnetic film disposed over a surface of the substrate. An insulator is disposed over the ferromagnetic film and at least one microstrip antenna is disposed over the insulator. The ferromagnetic film provides a non-linear response to the frequency conversion device. The frequency conversion device may be used for signal mixing and amplification. The frequency conversion device may also be used in data encryption applications.
