Keysight Technologies Millimeter Wave Technology and Test Instrumentation for V-E Band Applications Application Brief 02 | Keysight | Millimeter Wave Technology and Test Instrumentation for V-E Band Applications - Application Brief Situation analysis As users increasingly access the internet from mobile devices and use high-bandwidth services like high-definition video streaming, high-quality video conferencing, audio video downloads, and gaming, the demand for faster wireless broadband connections is growing. These applications have raised end-user expectations for network performance, which has contributed to the evolution of LTE networks and heightened the need to enlarge the capacity for backhauling data from base stations to the core network of carriers. To increase the data throughput capacity, high data rate (> 1 Gb/s) communication links are necessary. One emerging solution is to use wireless backhaul in the E-band. There is 10 GHz of bandwidth available in E-Band: 71 to 76 GHz and 81 to 86 GHz. There are other application fields available around the unlicensed 60 GHz band, such as WiGig (WiFi), and the planned 57 to 64 GHz band for short distance backhaul for the impending small cell telecommunication network. The latest semiconductor materials and new technologies have produced new transceivers that have made it feasible to better leverage these bandwidths. For example, Infineon's B7HF200 SiGeC bipolar technology with a transceiver family covering 57 to 64 GHz (BGT60), 71 to 76 GHz (BGT70), and 81 to 86 GHz (BGT80) bands. Figure 1 shows a schematic of how the Infineon BGT70 and BGT80 transceivers can be used in mobile communication backhaul applications. 03 | Keysight | Millimeter Wave Technology and Test Instrumentation for V-E Band Applications - Application Brief Full duplex system in FDD Base station A Base station B BGT 70 BGT 70 I/F I/Q I/F I/Q downconversion Rx On Tx On downconversion
