35 Qorvo 2022 suited for all Telematic Control Unit (TCU) eCall and antenna routing configurations. It also reduces insertion loss of up to 1dB, maximizing the effective power delivered to the external eCall antenna array and enabling better cellular and 5G connectivity, even in areas where signal coverage is limited. A compact design delivers up to 35% board area savings over traditional implementations that can require four or more discrete switches, associated matching, and months of engineering resources. This simplifies and speeds board design for multimode, multi-band systems. Using the fully integrated QPC1251Q and QPC1252Q for the eCall solution allows for a much more straightforward design—one chip does the job of five individual switches. This design approach can be used for 4G and 5G chipsets, eliminates multiple switches, lowers overall system power consumption, and allows automotive manufactures to connect primary and secondary antennas. The benefits of using either of these two highly-integrated components in a DSDA or non-DSDA solution include: • Flexible, single-component solution • Easy design solution enabling complex eCall antenna routing • Eliminates multiple switches and the need for RF matching on the TCU module • Allows for flexible switch control • Provides excellent insertion loss and isolation performance • Highly linear and offers low power consumption • A broadband solution suitable for 5G applications up to 6GHz • Integrated splitters, eliminating the need for external PC board or discrete splitters • A fully qualified AEC-100 Grade 2 solution Electronically speaking, our vehicles are becoming more complex—essentially becoming a new mobile device. As RF connectivity infrastructure becomes more available, our vehicles will become safer and more connected to each other and to our current wireless ecosystem. Integration of antenna electronics will help accelerate this mobile connectivity. Semiconductor companies like Qorvo are working diligently with vehicle manufacturers and standards bodies to provide highly-integrated solutions that help vehicle system engineers meet the needs of next-generation designs. With our integrated approach to the eCall switching system, we continue to work with customers to solve for the complex design requirements that ultimately help create best-in-class automobiles.
