Hi readers! Welcome to this in-depth look at high-frequency PCB design. When dealing with radio frequency, microwave, or high-speed digital signals, you understand that the choice of material can ruin or redeem your design. FR-4 may be wonderful for typical-purpose PCBs, but it tends to lack in sophisticated applications. That is where Rogers PCB materials step in.
Rogers materials are laminates of high-performance that Rogers Corporation has made specifically for employment in RF and microwave circuit design applications. Their substrates contain low dielectric loss, reliable dielectric constants, and less moisture absorption. These characteristics are important for signal integrity, in particular, in high-frequency situations when even small changes can result in decreased performance.
