These couplers tend to have about an octave bandwidth depending on the coupling level. Asymmetrical couplers are quite different and usually have variable coupling between the two transmission lines. WebThe coupling of a single-section coupled line coupler is limited in bandwidth due to the λ/4 length requirement. As in the case of matching transformers and waveguide couplers, bandwidth can be increased by using multiple sections [18]. Fig. 1. An N-section coupled line coupler (courtesy of [18]) A.
