What will happen if I don’t place them?
volker_muehlhaus said:Depending on the values, it can also be used for antenna impedance matching.
So if it can be used for impedance matching, then I do not have to worry about trace length, width and height?
However if this circuit is used for impedance matching, then if impedance is matched, why do I have to worry about line dimensions?
Do you mean that impedance is matched, but I have to think dimensions to match it exactly to 50 Ohms?
volker_muehlhaus said:But if we choose Zoutput = Zline = Zantenna, then we can choose the line length as needed, and there will be no additional impedance transformation.
1) From tranceiver's RFP and RFN outputs, the lines should be ideally like "twins" until they reach antenna, same length, width, curving etc, so that same impedance will be kept with each other.
2) If I use an inductance in series with the RF line, then inductor's ohmic resistance should be calculated in the total line impedance.
How can I calculate the RF line impedance?
1) Will 0805 size have negative effects on the RF part of the design, or is it OK to use them for now?
2) Is it better if those parts (independetly of their size) had round corners pads instead of 90 degrees angled? I heart it is better to have rounded pads.
