ABSTRACT:
A novel RF switch for switching radio frequency (RF) signals is disclosed. The RF switch may comprise both enhancement and depletion mode field-effect transistors (E-FETs and D-FETs) implemented as a monolithic integrated circuit (IC) on a silicon-on-insulator (SOI) substrate. The disclosed RF switch, with a novel bleeder circuit, may be used in RF applications wherein a selected switch state and performance are required when the switch and bleeder circuits are not provided with operating power (i.e., when the switch and bleeder circuits are “unpowered”).
