This letter presents a CMOS wideband variable gain LNA for 28-GHz 5G integrated phased-array transceivers preserving high third-order intercept point (OIP3) at all gain settings. The prototype LNA has ...

A 10-20 GHz tunable LC-VCO core using this inductor was also fabricated. Because of the multi-stage variable inductor, 20 GHz operation having over 10 GHz continuous tuning range with phase noise of ...
