A planar broadband phase shifter with wide range of differential phase is proposed. To achieve this performance, the design uses quarter wavelength parallel coupled lines combined with two L-shape networks. The L-shaped network includes a short-ended stub and a section of transmission line as an impedance transformer. The value of the differential phase can be adjusted through varying the coupling...
An ultra-wideband (UWB) phase shifter with wide range of differential phase shift is proposed. To achieve this performance, the design uses quarter wavelength parallel coupled lines combined with short-ended stub structure and an impedance transformer. The value of the differential phase can be adjusted through varying the coupling coefficient of the coupled lines along with the length and impedance...
