Design and optimization of a lumped-element balun for a zigbee wireless sensor node

Research output: Chapter in Book/Report/Conference proceedingsChapterpeer-review

Abstract

Because of the energy constraints of battery powered wireless sensor nodes, these systems require an energy-aware hardware design to provide adequate service lifetime. For such systems, the RF performance of the node is critical in terms of power consumption. An RF optimized node will reduce the number of re-transmissions needed during communication and will save energy and increase battery lifetime as a result. In addition, an RF optimized node will also allow greater communications range for a given transmit power, thereby reducing the number of nodes required to implement a given system with a resulting decrease in system cost. This paper presents the design, optimization and characterization of a 2.45GHz Zigbee node balun and matching network. The benefits of simulation and optimization are clearly highlighted by demonstrating an order of magnitude increase in communications range for the optimized node.
