June 2025 Issue
The June issue of the IEEE Microwave Magazine is out! This issue is almost 200 pages. And it ends with an IMS2025 Program Overview – check it out. As well as three features there are seven Student Competition Winners from IMS2024. These competitions cover everything from passive component designs to switch circuitry and power amplifier design. This issue will be distributed at IMS2025 so look for it. Our features are all about passive integrated circuits that serve multiple functions and are reconfigurable. And to make things even more interesting we have lots of columns covering many aspects of our society. Of course start this issue with the Editor’s Desk where you will get a full overview and then check the Guest Editor’s Desk where you will find out more about the features.
For a moment let’s focus on features and then talk about Student Design winners. Read about superconducting integrated circuit filters and MEM switches. Next read about how glass packaging is setting up 6G circuitry for success. Our final feature covers how liquid crystals have moved from displays to microwave circuits and antennas. Seven design contest wins testify to how our innovative students have been at it again. Find out how to design the widest band and smallest bias tee without using lumped components. Second, find out how to design a winning tunable matching circuit with high voltage solid state switches. Matching circuit design is a critical need in microwaves and our next winner has a tunable network which covers almost the entire Smith Chart. Carrying on with the bias network theme is a winner showing how bias networks can be tuned to improve Doherty amplifier performance. Next learn how 50 MHz and GaN can be a winner with a resonant gate driver. In recent years friendly filters which either pass power or absorb it (no reflections) have become popular and you can see how this winner solved the problem in our next to last design. Finally, 3D printers and antennas are a match made in heaven so learn about yet another innovative design.
Our society columns share a lot of information for members. Our President’s Column discusses all the collaboration that is needed by volunteers to put together the meetings, conventions and administration of our society. More society news is in that namesake column and it covers what has happened in 2024 with TC-2, our Design Automation Committee. We really enjoy awarding our society achievers and our Awards column celebrates all the IEEE Fellow elevations in 2025 for our members. Check it out and congratulate a friend. We spend a lot of time in education and our Education News column covers our wide ranging and fascinating webinars. Our Conference Report is all about the 2024 International Microwave and Antenna Symposium held in Marrakech, Morocco. We are clearly an international society and our MGA News covers the multi-society workshop held in Kerala, India. You know we have local chapters within our society and one of the new columns celebrates Featured MTT-S Chapters such as Ottawa. We have over 14,000 members and about 350 chapters. Women in Microwaves is now a regular column and a core event at our workshops and symposia. Find out about the 2024 IMWS-AMP workshop in Nanjing, China. And we also have our Reviewer Recognition column celebrating our Journal of Microwaves outstanding reviewers. Finally, we have another column regarding our IMS2025 symposium and that is the Industry and Advanced Practice Paper Competitions.
For the left side of the brain we will begin with MicroBusiness. We are all a part of bureaucracies and how do we keep them from expanding? We also have our New Products column with new cables, low noise amplifiers, load pull analysis based on oscilloscopes and phase shifters. Our Enigmas, etc. column covers our last month’s quiz with an answer sorting out Q in the reflection plane. As a fun end to this month we have a Speaker’s Corner with a tour of standards activities which are a crucial part of cooperation in our engineering life.
Please check out the IMS2025 Program Overview and our Conference Calendar. I hope to see you at the IMS.
