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 ...

SWR meters are used to measure the standing wave ratio (SWR) in radio equipment. They are sometimes called VSWR meters, a reference to voltage standing wave ratio (VSWR). SWR is the ratio of the ...

Co-sponsored by Analog Devices and Richardson RFPD. This webcast will provide a step-by-step approach to designing RF power and return loss measurement systems. The webcast will focus on a number of ...

If you are involved in any sort of radio transmission, you probably have at least heard of SWR or standing wave ratio. Most transmitters can measure it these days and most ham radio operators have ...
