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,…
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…
Check to select frequencies to calculate impedance. Check to highlight the copper layer of interest. Uncheck reference check box to designate a signal layer. By default, all layers are treated as a reference plane. 4. A ‘green’…
