Standing wave ratio (SWR) is the measurement of a type of impedance mismatch that can cause poor transmission efficiency in radio engineering. Impedance mismatch may cause standing waves along the transmission line. Advertisements Standing wave ratio is also known as voltage standing wave ratio (VSW...
Standing waves are a key value for any system using transmission lines / feeders where measurements of the VSWR, Voltage Standing Wave Ratio are important.
VSWR (Voltage Standing Wave Ratio) is the measure of how efficiently RF power is transmitted into a load. For example, if a power amplifier is connected to an antenna through a transmission line - ideally there will be no reflections and all the signal from the power amplifier will be trans...
By its definition, VSWR or Voltage Standing Wave Ratio is a ratio of peak voltage on the minimum amplitude of voltage of standign wave. It does not help much, does it? Okay, let's try to see how it relates ... In radio frequency systems, the characteristic impedance is one of the m...

When power enters an RF network, some enters the network, but dependent upon the impedance match, some of the power is reflected back to thee source. Note on Standing Wave Ratio, SWR & VSWR: Standing waves are often associated with RF feeders, and they are generated when there is a mis...
