Abstract
A variable phase shifter and a system for the variable phase shifter are provided. The phase shifter includes fixed phase shift elements, active devices for amplifying the outputs of the fixed phase shift elements, a combiner for combining the outputs of the active devices. For controlling the phase of the output signal, a bias controller is provided. The bias controller controls the bias of amplification in the fixed phase shift elements. The active devices may be FET or Bipolar Transistors, and are inductively connected to the ground. The phase shifter can be integrated into a system on chip with a smart antenna front-end system.
