So this was talked about in the comments of a previous question, but not in great detail:
I'm using a 2.4GHz ble chip, with a chip antenna. The recommended layout for this chip has a capacitor and an inductor to convert its output to a 50 ohm feed line. This feed line is going to be less than 1cm long before it hits my chip antenna.
Someone previously said that the characteristic impedance of my (pcb trace) feedline doesnt matter if it's that short (considering that the wavelength of 2.4ghz is around 10cm). Does this also apply to the characteristic impedance of the source, and the antenna? Can I get away with no pi matching network at all?
