摘要：
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 Delta phi 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 70 degrees/dB over a 30% bandwidth region. The second operation mode shows a 0 degrees-90 degrees differential phase shift with 0dB-10dB differential magnitude control with 10% bandwidth around 5GHz.
