What is the directivity of a directional coupler
Directivity measures a directional coupler’s ability to isolate forward and backward signals, typically ranging from 20 to 40 dB. Higher directivity, like 40 dB, ensures precise measurement of reflected power by minimizing interference from the forward signal, which is critical for accurate VSWR and return loss calculations. What Directivity Means In simple terms, directivity (D) […]
