Return Loss and SWR: Do They Represent the Same Thing?

Good impedance matching is required for the efficient transfer of signals between connected devices. Unfortunately a perfect match is rarely achieved. There are two common ways to express a device’s impedance mismatch:  Return Loss and Standing-Wave Ratio (SWR).  Both quantities describe the same phenomenon, but they have different interpretations. When a transmission line or waveguide … Continue reading Return Loss and SWR: Do They Represent the Same Thing?
