Abstract

A radio frequency (“RF”) circuit configured in accordance with an embodiment of the invention is fabricated on a substrate using integrated passive device (“IPD”) process technology. The RF circuit includes at least one RF signal line section and an integrated RF coupler located proximate to the RF signal line section. The integrated RF coupler, its output and grounding contact pads, and its matching network are fabricated on the same substrate using the same IPD process technology. The integrated RF coupler provides efficient and reproducible RF coupling without increasing the die footprint of the RF circuit.
