Abstract

A power diverter is presented. The power diverter includes a first ninety degree hybrid having one output coupled to a positive adjustable phase shifter and another output coupled to a negative adjustable phase shifter providing a negative phase shift. The value of the phase shift provided by the positive phase shifter and the negative phase shifter is the same amount of degrees but opposite. A second ninety degree hybrid combines the outputs of the phase shifters. The circuit is provided comprising only analog linear components such that no spurious signals are introduced, and the circuit is impedance matched on all ports such that no degradation of noise figure is introduced. The power diverter can also be configured as a programmable tap of a delay line.
