Radio has been around, in one form or another, for over a century. The early research into radio waves is even older than that. For Radio Design Group, radio’s history is a resource that yields a treasure trove of information. It was called "wireless" back then, a term which has come back into vogue in recent years.
The principles laid down by the early pioneers of radio are still just as valid today as they were a hundred years ago. Luminaries like Nicola Tesla, who first invented remote control via radio (vital to today’s drones), was also responsible for wireless power transfer, the basis for wireless battery charging that is just now becoming popular. Other names come to mind, such as Marconi, who helped make radio a practical form of communication, or Major Edwin Armstrong, who invented many of the methods and circuits that are still commonly used in wireless designs today. Other, perhaps more obscure contributions have come from unlikely sources: the actress Hedy Lamar is less famously known for her invention of the first spread-spectrum system, technology still used in military and cellular applications around the globe.
Since its incorporation in 1992, Radio Design Group has grown from a small RF consulting company specializing in small commercial markets to a vital contributor of unique and innovative products that have advanced the state of technology in both the commercial and defense related markets. Although continuing its tradition of innovative designs, the company has expanded the value of its services with high-quality manufacturing. No matter what the source, we still rely on the massive work done by those who have gone before us. When we design a new receiver, Major Armstrong is still whispering in our ear about frequency mixers and IF filters. When we create a new form of jam-resistant radio, Hedy Lamar’s work is not very far out of mind.
Again and again, we rely on old principles and methods, even as we design new, state of the art systems for commercial and military use. Our level of engineering excellence and innovative designs are now being carried forward as we stand on the shoulders of giants.
