What can an impedance mismatch in the RF cables and connectors cause?
An impedance mismatch in RF cables and connectors can cause excessive Voltage Standing Wave Ratio (VSWR). VSWR is a measure of how efficiently RF power is transmitted from a power source, through a transmission line, to a load. A high VSWR indicates that there is a reflection of the signal back towards the source due to impedance mismatch, which can result in signal loss and potential damage to the equipment.
answer is D
answer is D. 1. Voltage Standing Wave Ratio (VSWR) is a measurement of the return loss in a system. When it is excessive, it can cause damage to equipment.
D. Excessive VSWR CHAPTER 2 - PAGE 72-73 (Official Study Guide) "VSWR (Voltage Standing Wave Ratio) is a measurement of mismatched impedance in an RF system and is stated as an X:1..." "In an VSWR rating, a lower first number means a better impedance match."
