RF circuit with multiple-definition RF substrate and conductive material void under a bias line

An RF circuit includes a first dielectric material, a signal line and a bias line over a first surface of the first dielectric material, a conductive layer over a second surface of the first dielectric material, and a second dielectric material over the conductive layer. The first and second dielect...

description An RF circuit includes a first dielectric material, a signal line and a bias line over a first surface of the first dielectric material, a conductive layer over a second surface of the first dielectric material, and a second dielectric material over the conductive layer. The first and second dielectric materials have different dielectric constants. The conductive layer includes a ground plane over which the signal line is formed. A conductive material void, with which a section of the bias line is aligned, is present in the second conductive layer. The RF circuit further includes a mounting area for an RF device. First ends of the signal line and the section of the bias line are located proximate to the mounting area to enable the signal line and the bias line to be electrically coupled with one or more leads of the RF device.
