MAG became a California corporation in 1969 with the goal of supporting electronically scanning antenna (ESA) technology and other technologies where routing of RF signals is accomplished electronically. Towards this goal, MAG develops ferrite-based components and subsystems to allow realization of ESA systems and other electronically steered devices.

Production-quantity deliveries of components are provided economically and with good repeatability of outcome, but optimized for the particular system application. Designs are leveraged to fulfill newly discovered needs, while remaining faithful to proven ferrite-based technology.

MAG is equipped to serve military, government, aerospace, laboratory, and commercial markets with high-technology microwave component and system activities from applied research through volume production. Products manufactured include ferrite phase shifters plus a wide range of components for performing switching, circulator, isolator, variable power divider, and other radio frequency (RF) functions.

MAG has successfully provided components for synthetic aperture radar systems for over 30 years. Electronic scanning antennas (ESAs) have also been designed and manufactured by MAG. In addition, electronic drivers, beam steering controllers, and related electronic test equipment are produced as an offshoot of needs initiated by control of microwave components.

MAG products are found on land and sea and in the air, successfully deployed in many well known programs. These programs include those for aircraft landing control, air defense, warning and control, surveillance and tracking, fire control, weather observation, high altitude surveillance, threat identification, threat simulation, and laboratory and instrumentation. MAG also supports legacy systems, in some cases where the original manufacturer is no longer in business or willing to provide products produced in the past.

Production facilities include equipment for ceramic grinding, precision machining, thin film deposition, vacuum impregnation, chemical film processing, general assembly, and mil-spec soldering, each in its own dedicated area. A full complement of up-to-date laboratory apparatus for electronic and microwave measurements exists at MAG under real-time control by in-house computers that are interfaced with appropriate test equipment.
