A 2Gb/s 9.9pJ/b Sub-10GHz Wireless Transceiver for Reconfigurable FDD Wireless Networks and Short-Range Multicast Applications

Abstract

This paper presents a sub-10GHz wireless transceiver for short-range multicast applications in a reconfigurable FDD wireless network. The transceiver adopts a digital-process-friendly architecture and can deliver up to 2Gb/s data rate in a 500MHz channel bandwidth with 19.8mW power consumption and 9.9pJ/b energy efficiency. Being a coherent transceiver, it outputs -5.5dBm power, achieves -67.5dBm sensitivity at 1Gb/s and 1dB de-sensitization during FDD operation while tolerating -26dBm close-in Wi-Fi blockers.
