摘要: An embodiment of the present invention provides an apparatus, comprising a multi-tiered cascaded tunable dielectric phase shifter capable operating in digital-analog regime by at least one cascade operable analog and digital regime. The may be three tiered using broadside coupled lines with resonance terminations containing film capacitors. first two cascades regime, third further operate (0°/180° 0°/90°) between (0°÷90°), wherein provide states from 0° up to φN−1 add continuous shift functionality shifter. Also, providing 360° 5% bandwidth insertion loss approximately 3 dB without modulation. that enabled or more voltage capacitors which comprises low material metallic electrodes predetermined shape, size, distance.
