Impact of PCB structure on millimeter wave radar performance
ByGrace July 15, 2025July 15, 2025
Most common composite printed circuit boards (PCBs) use glass fiber as filler in their dielectric layers. However, due to the special weaving structure of glass fiber, the local dielectric constant (Dk) of the PCB board will change. Especially at millimeter wave (mmWave) frequencies, the glass weaving effect of thinner laminates will be more obvious, and…

PCB Characteristics and PDN Performance
ByGrace July 15, 2025July 15, 2025
Basic design rules for power distribution networks (PDNs) tell us that the best performance comes from a consistent, frequency-independent (or flat) impedance profile. This is one reason why power supply stability is important, because a poorly stable source will result in impedance peaks that degrade the flat impedance profile and the performance of the powered…
