Abstract
Official abstract text for this publication.
An integrated circuit for phase shifting a radio frequency signal, wherein the integrated circuit comprises at least one phase shifter comprising: at least one input for receiving a radio frequency signal, a voltage variable element; and a plurality of active devices operably coupled to the voltage variable element and arranged to receive a variable control voltage. The plurality of active devices comprise at least two active devices coupled in a common base arrangement and arranged to receive the radio frequency signal with the voltage variable element coupling the emitter contacts or source contacts of the at least two active devices, such that a variable control voltage applied to the voltage variable element adjusts a phase of the radio frequency signal.
