Abstract
An RF device includes a signal layer disposed over a ground plane having radio frequency (RF) transmission lines configured and dimensioned to provide impedance matching along the RF lines. A shield is formed as a part of the RF lines and disposed below the RF choke of a DC current supply to form an intermediate capacitance between the choke and the shield to control parasitic effects.
