Other parts in this youtube series: • Flawless PCB design: RF rules of thumb - P... In this series, I'm going to show you some very simple rules to achieve the highest performance from your radio frequency PCB design for your electronics project. I'll do this by showing you how to improve the grounding and reduce the crosstalk. These rules apply to both analog , digital and RF electronics. I'll also share some rules of thumb for PCB parasitics that you can use in electronics simulations. I'll prove my points with actual measurements on dedicated test PCBs. In this seventh part I'm showing what the impact of Q factor is on a high performance 30MHz LC low pass filter design. 0:00 intro 0:11 Q-factor explained 0:51 The low pass filter schematic 1:05 The filter PCB 1:14 Inductors used 2:15 Measurement setup 2:24 Measurement results 3:49 How to measure and calculate Q factor 6:27 Commercial break 7:03 Q-factor measurement results 1 7:44 Calculation example 8:20 Q-factor measurement results 2 8:55 Q-factor vs frequency for inductors 9:23 Home made air-core inductors Q-factor measurements 10:33 Sneak peak of next 4 videos 11:21 Relaxing end-screen......
