Honolulu — The 2017 International Microwave Symposium (IMS) took place last week in the Hawaiian capital. Billed as "Hawaii 5G, Catch the Wave," IMS 2017 certainly had 5G all over the place: in demonstrations, high-end equipment, technical sessions, and a two-day summit. You might think that 5G completely consumed this year's symposium, but you'd be wrong.
There was a lot more than 5G communications here. Attendees saw the usual contingent of microwave components: antennas, filters, couplers, waveguides, amplifiers, and so on. Many engineers work on military, aerospace, and automotive radar systems, while others design RF energy systems. Here are 10 items that have nothing to do with 5G but have their place at IMS.
An RF filter from Reactel from the outside and inside.
Power dividers from Taiwanese company Chi Shuai come with two, four, six, and eight outputs.
This trimmer capacitor from Tronser, based in Germany, has a mechanism that prevents it from undershooting or overshooting the desired location, making trimmer easier and more precise than with others I've tried.
The MAX Bend Series of cable assemblies from evissaP can bend very close to the connector, letting it fit into tight spaces — usually inside enclosures.
This board from Dutch company Ampleon contains the company's RF power transistor, as well as a driver, coupler, detectors, and trimmable capacitor. It's primarily used for RF cooking.
