An interesting thing is how as our target band goes up and up in frequency, the inductor becomes the easy part and the capacitor becomes an issue. The LC network can also serve as a lumped-element narrow-band matching network, and we use it on integrated circuits to tune out the gate capacitance of a MOSFET. And at some point we just give up on bias-Ts and switch to center-tapped transformers, where we use the center tap on both coils to bias the in/outputs of the system, and provide impedance matching.
Excellent video.
Seeing all those different cables - w2aew, do you make all your cables yourself?
