Switches

Microwave Applications Group (MAG) is well known as a supplier of ferrite microwave phase control devices since the 1960’s. U S Air Force AWACS E-3 Sentry aircraft, B-1B Lancer radar and many other programs have used ferrite devices developed, designed, and produced by MAG. Beginning in the 1990’s, we applied our experience to microwave switching devices. These switches use the principle of Faraday rotation to achieve a unique combination of high isolation, wide temperature range, and reciprocal operation at moderately high power levels. Our design capability extends well beyond these examples, and we invite inquiries regarding other specific applications.

L-Band Polarizer

This L-Band Polarizer sets a new standard for air-cooled ferrite control devices required to operate at high average power levels. Capable of switching between vertical linear and right-hand circular polarization, the L-Band Polarizer handles 65 kW peak and 6.5 kW average power. Maximum insertion loss is 0.4 dB, with 500 microseconds switching between states. The L-Band Polarizer allows the FAA LRR to switch between polarization modes dependent on weather conditions, providing feedback indicating the proper moment for switching.

Single Element Switch

The Tandem-Rotator Reciprocal X-Band Ferrite Switch uses 0° and 90° total Faraday Rotation states to achieve reciprocal connections to the desired ports. This structure operates at moderate isolation levels and moderate peak and average power levels compared with MAG bridge-type switches, but provides a smaller and less expensive package.

High Isolation Switch

This new compact High Isolation Waveguide Switch builds on MAG’s successful Single Element Switch, cascading these devices to yield a high isolation (less than 50 dB) switch that still handles moderate peak power levels of 50 kW and average power levels of 200 W in a compact, cost effective construction.

Toroid RF DPDT Waveguide Switch

Microwave Applications Group (MAG) continues to broaden its product line and is pleased to offer a non-reciprocal toroidal DPDT waveguide switch. This X-Band switch offers excellent performance over 12% bandwidth, and is a lower cost alternative to other switch architectures.

Resolvers

Airborne roll resolvers transform data from aircraft to other coordinates, whether looking down at the earth or maintaining satellite contact. Resolvers are also used where variable multiplexing is required.

Ferrite Waveguide Multiplexer

Ferrite Waveguide Multiplexers allow the user to configure connections between a number of RF inputs and outputs through a single device.
