Talking RLC Network Caixia Wu 1+ 1(Department of Electronic and Information Engineering ,Guangdong University Zhanjiang ,524088 ,China) + Corresponding author: Phn +86-, E-mail: 406126262@, Abstract :In the RF circuit, consisting of a passive components of the RLC network in the system to achieve a very important function,which is applied to the amplification, oscillation, modulation and demodulation of the units, and the most convincing is that they can be used to match the impedance or impedance transformation. This article will introduce several commonly used impedance matching network, as well as some mathematical formulas.
