As you can see in AN-2061 Wideband Bias Tee Design ...
Here I have two wonder/question:
1. suggested to use series inductance to mitigates resonances caused by interactions between L1 and the PCB. But how we can be aware of such resonances and how to calculate how to split our inductance to series inductances? Also I have found something similar in somewhere else:
2. Also how de-Q Resistors R2 and R3 reduce RF coupling from the PCB and filter out power supply noise.
