In modern electronic systems, radio frequency (RF) circuit board design has become increasingly complex and critical. With the rapid advancement of communication technology, from 5G mobile communications to satellite communications and radar systems, the performance of RF circuits directly impacts the quality and reliability of the entire system.
Impedance matching is a fundamental requirement during the design process. RF signal paths must maintain a consistent characteristic impedance, typically 50Ω. Any impedance discontinuity will cause signal reflections, degrading system performance. For microstrip or stripline lines, impedance can be controlled by adjusting line width and dielectric thickness; for differential lines, line spacing also needs to be considered. In practical applications, using an impedance calculator or electromagnetic field simulation software to accurately calculate impedance is essential.

Core Characteristics of Microwave RF Circuit Boards: Microwave RF circuit boards (PCBs) are designed for high-frequency signal transmission (typically 300MHz to 300GHz). Their core characteristics directly determine the performance ceiling of communication systems, radar, satellites, and other equipment. 1. Low-loss transmission of high-frequency signals. Low dielectric loss (Df): Utilizing low-loss dielectrics such as PTFE (polytetrafluoroethylene) and ceramic fillers (such as Rogers RO4000 series), Df values are as low as 0.001-0.003 (common FR4 has a Df of ≈ 0.02), significantly reducing heat loss of signal energy in the substrate. Low conductor loss: Surface treatment processes (such as immersion silver and immersion gold) optimize copper foil roughness (Ra < 0.5μm), suppressing signal attenuation caused by the skin effect.
