Abstract

This letter presents a general design methodology for compact layout of lumped element radio frequency (RF)/microwave matching networks based on partially overlapped inductors. We demonstrate the compact layout design approach on the output matching network of a TowerJazz 5.8-GHz SiGe power amplifier (PA) IP block fabricated in the 180-nm SBC18QH process. Our redesigned matching network achieves approximately a 20% footprint reduction. Small-signal measurements of PAs with original and compact output matching network designs, respectively, show virtually identical broadband performance.
