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.
