  • Abstract
    Based on the theory of metamaterial transmission lines, a phase shifter with independently controllable phase shift and line impedance is developed. The possibility of separate Deltaphi and Z L tuning reduces mismatch losses and leads to an increased performance, or can be applied for a combined phase shifter attenuator circuit. The presented phase shifter operates at a frequency of 6.5GHz with a FoM of 60 to 70deg/dB over a 30% bandwidth region. The second operation mode shows a 0deg-90deg differential phase shift with 0dB-10dB differential magnitude control with 10% bandwidth around 5GHz
