How Do Material Qualities Differ for HSD Versus mmWave Circuits?
Growing use of millimeter-wave (mmWave) frequencies for applications such as automotive radars, Fifth Generation (5G) wireless networks, and satellite communications (satcom) mandates careful selection of printed-circuit-board (PCB) materials specially formulated to transmit signals at frequencies to 70 GHz and higher. At the same time, digital…
Thousands of satellites surround the Earth in their own orbital slots and even their own constellations, at distinct altitudes. They help communicate with distant places, track weather, and, with the Global Positioning System (GPS), find distant places here on Earth. Closest to Earth,…
Fifth Generation (5G) wireless cellular networks promise performance that will meet every mobile user’s need, including reliable voice service, fast data, and steady video links. But such achievements will not come overnight, and they will call for a 5G network infrastructure with more cell sites…
