Coupler directivity is a function of the line spacing and electrical length of the lines. One …
WebMay 22, 2024 · Directional couplers are used to sample a traveling wave on one line and to induce a usually much smaller image of the wave on another line. That is, the forward- and backward-traveling waves are separated. Here a prescribed amount of the incident power is coupled out of the system. WebThere are numerous designs of directional couplers, such as coupled line sections (i.e. ¼ wavelength, multi-section or tapered), resistive bridges, Bethe hole couplers and many more. Implementation of such directional couplers may be on PCB (Printed Circuit Board), ceramic, metal structures etc.
