Do Materials Matter James Francey
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 signals are moving at higher…
