With the rise of Internet of Things (IoT) technology, it has become increasingly common for electronic products to be equipped with wireless communication capabilities. Wireless communication technology relies on RF circuits on PCBs to achieve this. Unfortunately, even the most skilled PCB designers often shy away from RF circuit design due to the significant design … Read more
Characteristic Impedance Characteristic Impedance (Z0) is an important parameter in transmission line theory, reflecting the impedance that transmission lines present to the propagation of electromagnetic waves. The characteristic impedance of PCB traces is related to the trace width, spacing, thickness, dielectric thickness, and dielectric constant. Since space can also be considered a type of medium, … Read more
