7 Qorvo 2022 The Qorvo QPF1002Q Automotive Front-End Module is an optimized solution for C-V2X (Cellular Vehicular- to-Everything) systems. C-V2X systems will sense the surrounding environment, enabling next-generation autonomy and real-time monitoring in connected vehicles. C-V2X uses the low-latency direct transmission in the 5.9GHz Intelligent Transportation System (ITS) band. The QPF1002Q also integrates a 5GHz power amplifier (PA), Tx/Rx antenna switch, and a bypassable low noise amplifier (LNA) into one single unit. This device features a 5.77GHz to 5.925GHz frequency range with a 28dB Tx gain, a 13dB Rx gain, and a low 2.6dB noise figure. Performance is focused on optimizing the PA for a 5V supply voltage that conserves power consumption while maintaining the highest linear output power and a leading- edge throughput. The receive path is pinned out for flexibility to enable external filtering or an LNA. The Qorvo QPF1002Q Automotive FEM is housed in a compact 5.0mm x 4.0mm x 0.925mm laminate package and is AEC-Q100 Grade 2 qualified for automotive system applications. The following are some key features: • AEC-Q100 Grade 2 qualified • 5.77GHz to 5.925GHz frequency range • Optimized for +5V operation; +4.2V capable • POUT = +28dBm, 10MHz linear power • 28dB Tx gain • 580mA Tx current • Tx High Power and Lower Power modes • 24dB Tx coupler • 2.6dB Rx noise figure (includes switches) • 13dB Rx gain • 35mA Rx current • -6.5dB Bypass LNA loss • No external matching required • 5.0mm x 4.0mm x 0.925mm laminate package • Halogen-free and RoHS compliant Applications are: • ITS C-V2X • Automotive front ends • Automotive telematics • Automotive infotainment C-V2X Sidelinking 5G, Release 16, brought sidelinking to industry C-V2X with 5G New Radio (NR). This release advanced C-V2X applications such as platooning, advanced driving, extended sensors, and remote driving. Strict latency and high reliability must be guaranteed because emergency braking and collision avoidance are needed in critical driving situations. C-V2X's smallest transmission latency is at most 4ms and can be lower depending on the implementation. It is difficult to quantify reliability here, but each new release has added another group of improvements in performance and safety, which has enhanced reliability. Upcoming releases are scheduled to continue on this path of safety and reliability improvements. The bulk of the traffic that will be carried out by short- range communications, especially in the first phase of V2X deployment, will be periodic broadcasting messages by each vehicle communicating its status and movements. Let's take a more in-depth look at one of the Qorvo FEMs, the QPF1002Q.
