With the growing number of apps, cloud computing, video streaming and other bandwidth consuming services the demand for mobile data services will continue to grow rapidly. To provide good Quality-of-Service (availability, fast speed, connectivity) at reasonable prices to the end customers the network operators also need the backhaul networks which have low latency, much higher capacity and lower total cost of ownership. Because of the wider bandwidths available in lightly licenced E-Band (71-76GHz & 81-86GHz), E-Band radio links are the right choice for Backhaul applications. Also ease of deployment, longer range and lower TCO is definitely an advantage for this technology. Infineon’s SiGe transceivers’ BGT70 and BGT80 based on its B7HF200 process and integrated inside the Embedded Wafer level ball grid Array package (eWLB) enable such a radio link. Infineon developed a RF front end system solution which operates at >3Gbps using QAM256 in 500MHz channel bandwidth.
