Triple Band Wireless Transceiver demonstrating Reliable and Low Latency Communication

Abstract

This work presents a fully integrated triple band wireless transceiver with integrated PAs for robust and reliable communication. With this transceiver a closed loop control system incorporating wireless communication is implemented achieving 425 µs latency with high reliability enabling applications in industry 4.0. With the presented transceiver architecture the unlicensed 2.4 GHz band and the ISM bands at 780-960 MHz and 390–510 MHz are supported with a single 1.5-2.0 GHz frequency synthesizer leading to an area efficient design and achieving interferer robustness by utilizing independent communication channels and bands. The chip has been fabricated in a 130 nm CMOS technology while the system is completed by off-the-shelf electronic components.
