Hybrid ring coupler
In this paper, a modified broadband hybrid-ring directional coupler is proposed. The 3D EM simulation results show that, from 75 GHz to 110 GHz, with an extra isolated arm, less than 0.25 degree phase difference and less than 0.03 dB amplitude difference are achieved by such coupler; in addition, a chamfer in the input arm increases the isolation between two output ports to more than 14.9 dB ...The hybrid ring coupler can be cascaded to form a multi-section configuration for bandwidth extension [17]. The bandwidth of a branch-line hybrid coupler can be improved by adding λ/2 sections to the inputs of the hybrid and by adding λ/2 length open stubs in parallel to the series branches [18]. Slotline crossover hybrid structures are usedApr 9, 2013 · Abstract: In this letter, a compact 3 dB 180°· hybrid coupler was proposed, designed, fabricated and measured. This device was derived from the classical hybrid ring coupler whose 3λ/4 section was replaced with inverting suspended microstrip line (SML). The proposed structure has a reduced size compared with the conventional and …
