PCL370HR RAILWAY Standard NFPA 130 BSS 7239 Approvals

Analog frequencies and digital data rates are increasing steadily in electronic circuits and systems, requiring careful choices of circuit materials for printed circuit boards (PCBs). Cellular communications technologies grew by means of RF and microwave signal frequencies, but Fifth Generation (5G) cellular wireless networks are…

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’…
