Abstract
A system comprises a differential phase shifter based on a differential coupled line coupler that can include a ground metal layer, a bottom metal layer and a top metal layer. The differential line coupler can include differential input lines comprising two metal stack layers (top and bottom), which are arranged diagonally, and the differential output lines are arranged in a complementary diagonal configuration. This layout configuration overcomes the asymmetry caused by the difference in metal layer thickness and width difference, as well as a periphery effect such as the distance to a ground plane or substrate. The proposed diagonal layout configuration balances the characteristic impedance and phase accumulation on each coupled wire of the differential coupled line coupler, which improves the performance of the phase shifter, e.g. lower insertion loss and wider phase tuning range.
