Impedance matching network for low output impedance devices

摘要

An impedance matching circuit which includes an RC network placed at the end of the transmission line and which will absorb reflections. The values of the resistor and capacitor are selected such that the output voltage at the end of the transmission line is attenuated only during the duration of the reflected waves and the overall gain from the incident signal to the end of the transmission line is 1:1. The values of the resistor and capacitor selected are based upon the impedance mismatch and the length of the transmission line.
