Abstract:
1. 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, comprising the steps of: identifying parasitic electromagnetic elements associated with an RF choke for a given placement on a substrate; placing and dimensioning RF lines on a 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 matching and control of parasitic effects of the RF choke are simultaneously provided wherein an intermediate capacitance formed between the RF choke and the shield is sized to balance against the parasitic effects to provide a desired transmission response over a selected frequency range wherein the intermediate capacitance and impedances of the parasitic effects form a circuit which controls the parasitic effects; and balancing between the intermediate capacitance versus the parasitic effects to provide a flat or peaked transmission response over a selected frequency range, wherein the balancing includes establishing C
