A Miniaturized Multi-section Transformer on Si RFIC for Low Impedance Transformation in UWB

A highly miniaturized and broadband impedance transformer was developed for application to broadband low impedance matching, using a coplanar waveguide employing a periodically arrayed grounded-strip structure (PAGS) on silicon substrate. The multi-sec...

In broadband communication systems, such as ultra-wideband (UWB), low impedance transformation is required for impedance matching between active devices because the input and output impedances of the FETs are much lower than 50 Ω in the RF band. 1 Therefore, for efficient impedance matching in a radio frequency integrated...
