A method for fabricating a transceiver, which simultaneously provides impedance matched transmission for radio frequency (RF) and shields against transmission losses due to parasitic effects includes identifying parasitic electromagnetic elements associated with an RF choke for a given placement on a substrate. RF lines are placed and dimensioned on the bench to form impedance matched RF lines wherein a portion of the RF lines shield the RF choke for a given bandwidth such that impedance matchin...
