I own Peak Gain Wireless, LLC, which provides wireless product design and development services. Our team has expertise with Bluetooth, Bluetooth Low Energy(BLE), WiFi, Zigbee, wireless sensors and other sub 6GHz ISM radios. Many of our designs are low power RF running on disposable batteries or coin cells for app enabled connectivity. Our services include system specification development, hardware, firmware, antenna design and test and measurement. We offer both full turn key design services, or we can help your team succeed with the high risk RF parts of the design such as antenna design, tune and final integration into the end product. We support single and multiband antenna design and development including antennas for cellular M2M products. We also offer antenna pattern measurement service to quantify the performance of antenna components and antennas integrated into products. Our clients own all source code and circuit board design files at project completion.
We are often called upon to solve radiated emissions and noise problems as it relates to regulatory compliance and product performance. Neglecting the antenna design, no design provisions to address emergent radiated emissions problems or lack of experience to understand and mitigate design risk can quickly destroy the budget and schedule. If you engage us early in the design cycle, we can help you avoid the common and uncommon mistakes. We’ll help get your product to market on time and on budget.
President and Principal RF Hardware Consulting Engineer @ Peak Gain Wireless is committed to providing wireless design expertise that achieves optimal RF performance. We realize the last few dB of RF performance is typically the most challenging to achieve, but critical to development of market-leading solutions. We help make your wireless world a better place including Bluetooth, Bluetooth Smart, WiFi, Cellular M2M, Zigbee, LoRa or any ISM band radio below 6GHz.
