Self-calibrating voltage standing-wave ratio meter system

摘要: A circuit for use in connection with a meter measuring the voltage standing-wave ratio (VSWR) along transmission line wherein forward and reflected voltages are coupled off detected by two respective diodes. Calibration of diode reverse occurs series resistor-diode combinations before they fed onto base collector, respectively, transistor. connected between collector emitter transistor measures drop across this value is proportional to ratio.
