December 2025 Issue

The December issue of the IEEE Microwave Magazine is out! This year is almost over. And our December issues celebrate the coming of Radio & Wireless Week. That means this issue has columns describing the entire week and features focusing on 6G, training signals and wireless power. As usual, if you want the best overview of this issue check out the Editor’s Desk but for now we will try to give you a quick breakdown.
First let’s discuss the features. 6G is coming and our first feature gives an in depth overview. We all know how much machine learning and AI has changed things and training is fundamental to that as well as digital predistortion and power amplifier modeling as discussed in our second feature. The more we communicate and compute the more clock phase noise and jitter matters so our third feature focuses on these fundamentals for 6G and quantum computing. Our final feature covers a twist on wireless power transfer where it adapts to location. Next let’s talk about what’s happening during Radio & Wireless Week (RWW).
Your next two columns are the Welcome column and the Technical Program Chair’s Message so you know what is happening in RWW. Next we have eight columns covering the other conferences, meetings, summits, workshops and events. There is something in RWW week for everyone. Just to name a few there is a power amplifiers conference, a meeting on silicon ICs for RF systems, a space hardware conference, a topical conference on sensor networks, the ARFTG conference, an IoT summit, workshops for the week and a Women in Microwaves and Young Professionals event. Just go, you will learn a lot and enjoy yourself. Not to mention meeting lots of great people.
Our regular columns could be divided into society news and technical thoughts. On the society side check out the President’s Column for an overview of this past year in the MTT society. Next year we will have a new President. And for this issue check out the Guest Editor’s Desk and learn about all that went into this issue and is to come during Radio and Wireless Week. We have conferences all over the world and our MGA News column will give you a tour of what has happened with our Kerala Chapter Workshop. Next the MTT-S Society News gives a tour of what has been happening in the North Italy Chapter. We really value our young professionals and this month’s column covers what happened at the Antennas & Propagation Conference. Finally our MTT-S Ombudsman Officer solves a number of questions and problems for members. Check it out.
For thinking columns I like to start with MicroBusiness. This month we consider homogeneity. And that reminds me of an old friend that said “If two people agree on everything then one of them is redundant.” Contribute, don’t be redundant. Our Health Matters column works hard to provide the leading research on the effects of microwave exposure. We live with microwave radiation every day and the engineers want to know the risks. Check out the results of the Japan-Korea collaboration. Our recently introduced Microwave Spectrum Policy column gives a preview of the 2027 World Radiocommunication Conference so check it out to learn about what is happening in radio spectrum usage. Education is key. Our Educator’s Corner always helps push us forward. Physics changes slowly but new ways of looking at things always helps. Check out how the figure of merit kQ can simplify many problems. Puzzles are fun. This Enigmas, etc. column shows us the answer to last month’s power transfer question.
As always, take a look at the Conference Calendar and enjoy meeting and talking with others.
