Behzad Razavi Keynote: “The Future of Radios”

It is a cold morning. You get into your car and mutter, “Office.’’ While the car begins to navigate the road, you remember today is your spouse’s birthday, whip out your Iphone15, and order a gift, knowing that a drone will drop it off in the afternoon. Now you can catch up with the day’s news during the 30-minute drive to your office, watching videos streaming down from microsatellites up in the heavens. It is the year 2025. Isaac Asimov would have been proud.

Whether or not technology giants such as Google, Apple, and Amazon will bring this vision to reality, they and most other elements of our civilization will increasingly rely on wireless communication. This paper offers perspectives on how the radios in our wireless world will evolve and what challenges they will present to RF designers. Specifically, one can contend that the mobile terminal is likely to further widen its role in our lives and serve as a central command post. It will pay our bills, control our homes, direct our vehicles, communicate our vital signs, and possibly transmit our thoughts. One can also predict three trends in mobile terminal design: (1) the use of “universal radios,’’ radios that seamlessly accommodate many bands with minimal overhead and operate with higher data rates; (2) omission of off-chip filters through architecture innovations; and (3) greater emphasis on low power consumption. Examples of these concepts are presented.
