What is RF Front End (RFFE), and what part does this critical mobile technology play in delivering advanced RF-Modem systems? These are just the first two answers that Futurum senior analyst Olivier Blanchard answers in this three-part series about how RFFE is already solving the growing engineering complexities of 5G, perhaps chief among them how to elegantly solve mmWave challenges, deliver high performance solutions like Qualcomm’s X65 modem-RF system, and provide high speed, low latency connectivity to mobile devices, vehicles, and IOT devices.
