Microwave PCB design presents unique challenges that differ from lower frequency boards. At microwave frequencies (1 GHz to 30 GHz), the short wavelengths and high signal speeds introduce impedance mismatches, signal loss, crosstalk, and EMI. The demand for microwave and RF PCBs is rapidly increasing, presenting significant growth opportunities in both global and U.S. markets. For statistics, see antenna integration and RF design guidelines for 5G PCBs. When designing printed boards for microwave frequencies, addressing parasitic elements, managing the skin effect, and controlling transmission line behavior become critical. These factors complicate the design process, as small variations in layout can…
