E-band spectrum at 71 to 76GHz and 81 to 86GHz offers worldwide availability of wide operating bandwidths under a light license system [1]. This makes it attractive for very high data rate applications such as cellular backhaul. The development of E-band radio front-ends with adequate performance at commercially acceptable prices holds a number of significant challenges. These include component availability, performance and cost as well as the engineering difficulties associated with implementing and manufacturing the radio. This paper describes these challenges and discusses the best approaches for addressing them.
