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.
