About Us

Plexsa originated as an electronic design company in 1995. We have since grown to specialize in broadband RF multiplexers and filters. By focusing our efforts we have made extensive breakthroughs in the design and manufacturing of suspended substrate stripline technology. We continually push the bounds on what is possible for broadband multiplexers and filters and can confidently say that we are world leaders in this field.

We discovered early on that the only way to ensure consistent production quality is to perform the processes in-house. Over the last two decades each process has been researched and fine-tuned to maximize the potential of suspended stripline technology. Our manufacturing is thus highly specialized and allows us to make products of unsurpassed accuracy and conformance to the most stringent specifications. Plexsa also benefits from rapid prototyping, allowing flexibility and adaptability.

We continually develop new products and further constantly improve our design and production processes and capabilities. Since we frequently custom design to client specification, we are always working to ensure evolving and unrivalled product solutions. Plexsa strives to always lead in broadband multiplexer technology, while offering the highest value at the lowest price.

Having relocated from South Africa to Hungary in recent years has allowed us to further improve on all our technology as well as make it easier for us to deal more directly with clients and suppliers.
