RF Engineering


At Optimal Design we have a passion for all things wireless. Our team of industry leading wireless experts are involved early in the our multidisciplinary process to ensure optimal range, throughput, and signal integrity for all wireless solutions. Our RF design engineers and Antenna design experts work closely with our customers to define system requirements and create solutions tailored for their unique business case.

We engage our RF design skills up front in our “Design for Electromagnetic Compatibility” process. Design for EMC means establishing the groundwork for interoperability and regulatory agency compliance from the beginning of the design process to avoid costly late phase design spins.

Optimal Design’s experienced RF Engineering team gives our customers the option of fully integrating custom designed antenna systems into their size constrained products or custom applications, as well as using off-the-shelf industry standard RF modules.

Optimal Design’s RF design and engineering capabilities include:

    • WiFi Bluetooth
    • Bluetooth Low Energy (BLE)
    • Cellular
    • LoRa
    • GPS
    • NFC
  • Wireless system range extension
  • Antenna design, simulation, and testing
  • BLE to WiFi bridging
  • Design for EMC
  • End to end system link optimization
  • Electromagnetic interference mitigation
  • Analog / Signal Processing
  • Single and co-located radio designs
  • Schematic Capture / PCB Design & Layout
  • Regulatory agency compliance testing
