Wireless/RF Design 

In this age of pervasive wireless communications with offers of “free” cellular phones every day, WiFi hotspots at every coffee shop, and cordless phones in every home, consumers now take radio technology for granted.  In today's market, a large percentage of electronic products use radio technology to eliminate wires and maintain connectivity with the outside world.

Despite the complex design and physics involved the public expects new electronic products to incorporate radio communications that simply work.

Due to the complexities of radio propagation, high-frequency circuit design, and regulatory issues, there are many hurdles on the way to getting radio connectivity into your products.  Developing a wireless product requires specialized expertise and equipment and involves many challenges, such as radio interference issues and integrating the antenna into the package.


Whether you need a simple short-range wireless link or a complex radio network designed, PDE has the expertise, experience and equipment to make your wireless project a success.  We have many years of experience designing radio systems for a wide range of products – from simple, low-cost 27MHz radios for wireless computer peripherals to very complex 2.4GHz spread spectrum systems.

Along with our other in-house capabilities such as embedded microcontroller design, mechanical design and printed circuit board design, we provide a complete solution for your wireless product design and we can take it all the way from concept through regulatory testing into production.

“We were looking for a product design subcontractor that would assume responsibility for multiple aspects of our project.  PDE took charge and developed a good understanding of all the elements of the project.  They were committed to the product and integrated very well with the other consultants on my team.

PDE’s comprehensive capabilities and expertise in Mechanical, Electrical, Wireless and Firmware design were a major factor in achieving a successful outcome for our product, which differentiated them from other design firms. I am very satisfied!"
