Compact Layout Redesign of Output Matching Network of a 5.8-GHz SiGe Power Amplifier
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.

Extraction of SOS MOSFET RF equivalent circuit elements by LCR meter measurements
Two methods for the extraction of the small-signal equivalent circuit of high frequency silicon on sapphire (SOS) MOSFETs are compared. One technique employs microwave vector network analyser measurements in the 0.2–24 GHz range, while the other uses a low frequency LCR meter at 100 kHz to determine the circuit element values. Results presented show excellent agreement between the two methods. It is concluded that the low frequency method can be successfully used to extract high frequency circuit-model elements and reasons for this are offered.
