| Abstract: | In order to get the effect of impedance transformation, it often involves selecting the low impedance coaxial cable to make balun when making the RF power amplifier. For the coaxial cable, according to the standard configuration, the article will presents the key parameters of changing the structure to obtain a low impedance coaxial, then theory test methods are deduced, and we get the simple method of low impedance coaxial cable testing and validation by using adjustable resistor. |
