Patent ID: 8922306

Claim:
A system, comprising: a substrate having a top layer, a bottom layer, and at least one internal layer; a first radio frequency (RF) port; a second RF port electrically coupled with the first RF port; an RF microstrip integrated with the top layer of the substrate, wherein the RF microstrip couples the first and second RF ports; a direct current (DC) port; and a bias tee incorporated into the substrate, the bias tee comprising: a first capacitor comprising a first catch pad integrated with the top layer of the substrate, wherein the first catch pad is electrically coupled with the first and second RF ports; a second capacitor comprising a second catch pad integrated with the bottom layer of the substrate; a connecting pin passing through the at least one internal layer of the substrate, wherein the connecting pin is electrically coupled between the first catch pad and the second catch pad; and an inductor at least partially integrated with the bottom layer of the substrate, wherein the inductor is electrically coupled between the second catch pad and the DC port.
