Coupled line coupler
Transdirectional coupled-line couplers have the benefit of perfect input/output isolation. However, for a coupled-line coupler to operate in transdirectional mode, both phase- and impedance-coupling are required, which is difficult to meet by traditional coupled lines. To overcome this problem, this paper presents a novel …branch-line coupler, the coupled lines coupler and the Lange coupler which is an extension of the coupled lines proficiencies. One of the most popular passive circuits used for various microwave and millimeter-wave applications is a branch-line directional coupler. In this paper, digital models of different couplerA wideband 90° microstrip hybrid coupler with a bandwidth of 84.3% is proposed. The hybrid coupler consists of a two-section coupled-line power divider and a 90° phase shifter. The two-section ...

The coupler consists of two coupled lines with tapering characteristic impedance over the length 0 < z < L.At z = 0, the lines are very weakly coupled, so that the even- and odd-mode impedances are equal to the characteristic impedance of the line Z o.While at z = L, the coupling is such that even-mode impedance becomes Z o /k, and …About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...The schematic representation of the arbitrary phase-difference coupled-line coupler with tight coupling is illustrated in Fig. 2a.Two coupled-line sections with even- and odd-mode impedances (Z e and Z o) and the electrical length (θ 1) are connected in cascade by two delay lines with the same impedance Z 2, but different electrical lengths (θ 2 and θ 3).

Zai di , et al.Lines can be coupled in at least three ways: Edge coupled. Broadside coupled. End coupled (used in filters but not used in couplers) In order to make a quadrature coupled-line coupler you need to couple a quarter-wave section; end-coupled structures are not useful in this case. 4/20/2009 Analysis and Design of Coupled Line Couplers 2/11 Jim Stiles The Univ. of Kansas Dept. of EECS To determine these four elements, we can apply a source to port 1 and then terminate all other ports: Typically, a coupled-line coupler schematic is drawn without explicitly showing the ground conductors (i.e., without the ground plane): βAAdditionally, the image indicates the X Y / Z control lines, readout resonators, readout lines, and airbridges.
