Abstract
Ultra linear silicon-on-glass varactor topologies with improved power handling and linearity have been realized. The resulting components include integrated bias networks and provide excellent low-loss performance for large capacitances (e.g. C=20pF Q>100 at 2GHz with Vcont=2V). Using a novel center tap circuit the linearity has been improved for narrowband two-tone signals yielding measured IIP3V values above 75V for tone spacings >10kHz. By implementing two varactor stacks in series with integrated bias networks the power handing improves 4x, while the IIP3V doubles. The resulting devices can be used as flip-chip components enabling linear adaptive wireless applications.
