A standing wave may be formed when a wave is transmitted into one end of a transmission line and is reflected from the other end by an impedance mismatch. The Voltage standing wave ratio is the ratio ...

Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...

A 105 MHz, 90 V peak signal is incident on a 50 Ω transmission line. The velocity factor k of this line is 0.85. The line is 125 meters long and is terminated in a 300 Ω load. See Figure above. a) ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...

Here’s a situation that creates fear and trembling: The engineer receives a call from the radio station: “The transmitter is off the air and there is a VSWR fault.” If the station is fortunate, the ...
