IEEE INTERNATIONAL MICROWAVE SYMPOSIUM (IMS) 2023, SAN DIEGO. Advanced electronic-circuit firm Isola Group is showing its lines of laminates and prepreg materials for RF, microwave, millimeter-wave (mmWave), and photonics circuits at this week's IMS show in San Diego. 

CHANDLER, Ariz. Isola Group, one of the world’s leading developers and suppliers of copper-clad laminates and prepreg materials for printed circuit boards (PCBs), will be inviting visitors to the 2023 IPC APEX EXPO to learn more about its low-loss circuit materials. Isola’s material experts will offer guidance on its latest halogen-free TerraGreen® 400G series of circuit materials for halogen-free PCBs.

Fifth-generation networks, known as 5G, offer extensive wireless services with even faster data rates to come for such uses as military and mission-critical communications, enhanced mobile broadband, and the massive Internet of Things (IoT). Most of the systems to date have been based on signals below 6 GHz. Once network coverage has been achieved at higher millimeter-wave (mmWave) frequencies of 24 GHz and higher, 5G networks will support multigigabit upload and download speeds. Distributed network coverage at those higher frequencies will require many small cells with printed circuit boards (PCBs) capable of RF, microwave, mmWave, and high-speed digital (HSD) operation. Those small cells will demand PCB materials with high performance and reliability through mmWave frequencies, and with characteristics well suited to the operating environments of both indoor and outdoor 5G small cells.

Isola Group, a global innovator in materials for printed-circuit boards (PCBs), has announced its low-loss I-Tera MT40 circuit materials supporting multilayer printed circuit boards (PCBs) for military- and commercial-grade low-Earth-orbit (LEO) satellites.

To meet the constant consumer demand for higher bandwidth in their wireless devices, companies have developed ultra-wideband communications equipment and advanced wireless techniques, such as frequency-hopping spread spectrum transmission, in which radio signals are rapidly switched between frequencies. The same technique can also guard against eavesdropping. With those advances, however, comes a growing challenge for manufacturers of the high-performance printed circuit boards aimed at the wireless communications market. That challenge lies in controlling a phenomenon known as Passive Intermodulation.

Counterfeit electronics are becoming increasingly common in the marketplace. These counterfeits can lead to problems with product safety and reliability, a risk for end users of the products that incorporate them. It’s possible, however, to minimize the problem by being aware of it and taking proper steps to identify parts and mitigate the issue.
