REALISTIC TRANSISTOR MODEL Figure 10 VSWR circle and loads seen by each side of the balanced amplifier under a 5:1 output mismatch, as the phase of the external mismatch is rotated through 180 degrees. WebThe VSWR is a figure of merit for impedance match (or mismatch). In an attenuator, it is a measure of the deviation from 50 or 75 ohms of the component’s input and output impedances. A perfect match is represented by a VSWR of 1.0:1, while a worse-case mismatch is represented by an infinite VSWR of ∞ : 1.
