Abstract

In this paper a GaAs MMIC phase shifter, based on a lumped quadrature hybrid, is described. The MMIC makes use of two interleaved spiral inductors in a transformer-like configuration to implement the quadrature coupler function. Two L-C resonant networks connected as load, provide the desired analog phase swing, under electronic control thus resulting a phase-shift capability of nearly 180°.
