ABSTRACT:
An active device, such as a field effect transistor ("FET"), converts microwave signals between a slot transmission line ("slotline") and a coplanar waveguide ("CPW") In slotline-to-CPW conversion using one or more FETs, a gate connection is made to one or both of the slotline conductors. A drain connection is made to the center conductor on the CPW. Two FET source terminals are connected respectively to each CPW ground strip and may be coupled to a slotline conductor. The active device can be reconnected so as to reverse the input and output, providing for conversion of signals from CPW to slotline. Conversion between balanced-signal slotline and CPW further includes passive or active phase shift of one signal path.
