Why Choose Rogers CuClad 217 for High-Frequency PCBs? A Look at Dk, Df, and Isotropy Selecting the right laminate is a primary decision in high-frequency PCB development. Standard materials like FR-4 are not suitable when signal integrity is required above 500 MHz. For radar systems, aerospace communications, or microwave components, the substrate material directly affects circui...
How Does Nickel-Free EPIG Improve PIM Performance in Base Station Antennas? Passive Intermodulation (PIM) is one of the most critical performance killers in modern cellular infrastructure. In a base station antenna system, PIM appears as unwanted interference generated by passive components—connectors, cables, and the printed circuit board itself—when two or more high-power transmit signals mix. E...
