Matlab based on the RF circuit design and simulation
ABSTRACT
This paper introduces the general RF systems, introduced in the radio frequency (RF) circuit design Smith chart an important role in the development of the machine, and then Smith introduced the basic principles of map, also introduced the S-parameters of transistors. Focuses on the use of MATLAB to the RF amplifier module system design simulation of a round Figure, and through examples, have been designed in line with the circle diagram. And the text of the RF transistor amplifier design of the basic theory of knowledge expounded in detail on the amplifier to the definition of performance indicators, but also describes the use of circle equation stability, gain, noise and VSWR indicators. And concluded, MATLAB can be effectively used in the RF system design, the microwave circuit simulation to achieve the circular map, we can provide the majority of RF circuit designers of great help.
