摘要： 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.

摘要： A device 20 includes a substrate 22 coupled with a substrate 24 such that a volume 32 is formed between the substrates 22, 24. Contact posts 48, 50 on the substrate 22 and a cantilever beam structure 36 on the substrate 24 are located within the volume 32. The cantilever beam structure has a conductive trace 38 that is selectively contactable with the contact posts 48, 50 to yield a microelectromechanical (MEMS) switch within the volume 32. Fabrication methodology for making the contact posts 48, 50 entails forming post protrusions 68, 70 on the substrate 22 and shaping post protrusions 68, 70 so that they acquire a rounded shape. Input and output signal lines 42, 44 are constructed such that respective portions of input and output signal lines 42, 44 overly corresponding post protrusions 68, 70 and take on the shape of post protrusions 68, 70.
