AST's broad line of Waveguide, Coaxial & Dual Switches stem from 40 years of microwave experience.

Since our founding in 1992, AST has shipped over 30,000 switches to more than 100 countries

Our commitment is to give our clients a top quality product with a very fast delivery .
All AST switches undergo stringent testing to guarantee performance, including activation 2,000 times, putting the switch underwater to guarantee that it is fully sealed,  and checking waveguide performance on state of the art network analyzers.
On our switches we offer any waveguide flange at no extra charge and can offer a wide variety of wiring options with up to 4 C-form contact or inhibit circuits.
In addition, since the 2017 merger of Diosat Satellite and AST, AST can now provide a wide range of waveguide products such as waveguide bends, terminations, and flexible waveguide. This saves our customers time.
Lastly, all AST products 3 year limited warranty.
