Coupler Directivity Equation at Margaret Steen blog

Coupler Directivity Equation. in this article, we’ll discuss how the directivity factor of a coupler can introduce error when measuring reflected power. in the terminology of the directional coupler, we say that port 1 is the input port, port 2 is the through port, port 3 is the coupled port,. A directional coupler is often used for sampling a small portion of the signal power. directivity (d) the directivity of a directional coupler is the ratio of forward power to the back power, measured in db. For example, we might measure the output power of the coupled port. Directivity is typically in the range of 30 to 40 db. an ideal coupler has infinite directivity and isolation, along with a coupling factor selected for the intended application. $$i ~=~ c~+~d$$ equation 4. The functional diagram in fig. 1 illustrates the operation of a directional coupler, followed by a description of the related performance parameters. directional couplers are used to sample a traveling wave on one line and to induce a usually much smaller image of. the directivity (as well as the isolation) factor is a measure of the coupler’s ability to separate forward and backward waves (more on this shortly). From the above equations, you can easily verify that the three quantities are related by:
