Power amplifiers for ultra-energy-efficient long-range IoT radios

Aurora Wireless Networks是一家加拿大公司，设计和制造超节能的远程无线电设备。Aurora的产品经过特别设计，可提供长距离通信，同时为电池供电的多年运行提供低功耗。Aurora Wireless NetworkShelps客户端开发和/或部署最节能、远距离、无许可证、可用的无线数据网络。无论是物联网开发的一部分，还是创新的工业遥测，Aurora Wireless Networks都为可靠和具有成本效益的产品提供硬件和软件构建块。作为Aurora无线电发射机的关键部件，功率放大器的供应商最近宣布功放过时，从而要求Aurora寻求替代的高性价比解决方案。由于最初的工作表明，现有的替代解决方案是不够的，所以定制的解决方案被提出。拟议的研究目标是帮助重新设计将在卡尔加里生产的Aurora WirelessNetworks产品之一的发射机系统。Belostotski在卡尔加里大学(UofC)的研究团队在宽带射频收发系统的设计和开发方面获得了重要的实用专业知识。这种专业知识与Aurora面临的挑战非常匹配，预计将帮助该公司重新开发其下一代产品，并保持其市场份额。拟议的项目正在努力帮助该公司开发一种微型、高效的功率放大器。在NSERC Engage资助金支持的一段时间内，UofC团队将致力于确定能够达到预期性能要求的功率晶体管或系统，通过模拟演示建议的放大器的性能，设计和开发功率放大器的电路板级别实现，并对放大器的运行进行实验验证。

Aurora Wireless Networks is a Canadian company, which designs and manufactures ultra-energy-efficient,long-range radio equipment. Aurora's products are especially engineered to provide long communication rangewhile consuming low amount of power for battery-powered multi-year operation. Aurora Wireless Networkshelps clients develop and/or deploy the most energy efficient, long range, license free, wireless data networksavailable. Whether part of the internet of things development or innovative industrial telemetry, AuroraWireless Networks offers the hardware and software building blocks for reliable and cost-effective products.The supplier of a power amplifier, a key component of Aurora's radio transmitter, has recently declared theamplifier obsolete thereby requiring Aurora seek an alternative cost-effective solution. Since initial workshowed that available alternative solutions were inadequate, a custom-made solution is sought.The proposed research targets to assist with a redesign of a transmitter system in one of Aurora WirelessNetworks products that will be manufactured in Calgary.Dr. Belostotski's research team at the University of Calgary (UofC) has acquired significant practical expertisein design and development of broadband RF transceiver systems. This expertise matches well with thechallenges faced by Aurora and is expected to help the company with redevelopment of its next generationproducts and maintain its market share.The proposed project is striving to assist the company with the development of a miniature, high-efficiencypower amplifier. During the period of time supported by the NSERC Engage grant, the UofC team will aim toidentify the power transistors or systems capable of achieving expected performance requirements, demonstratewith simulations the performance of the proposed amplifier, design and develop a circuit-board-levelimplementation of the power amplifier, and perform experimental validation of the amplifier operation.
