Design of RF Impedance Analyzer

Abstract: This paper uses the precision ADC LM12H458 and the low noise operation amplifier LM722 to constitute a low-cost, precise RF impedance system, using a model with a traditional radio frequency impedance measurement, calculating unknown radio frequency impedance by measuring three scales voltages, respectively. Numerical value. The design principle and implementation method are set forth herein. The first part of the article, the second part of the article, the third part of the article, article map, technology area Talking about the Development, Content and Application of EDA Technology Talking about the role of PowerPCBLAYER25 layer Where is China EDA development? Break through the point to the whole industry chain PCB upstream material rose a new high price for nearly 6 years without stopping Fujo Designed a high-end product, the high-speed design layout cannot be ignored!
