摘要
Abstract
The paper brielfy introduces the basic theory of iflter, a RF high-pass iflter is designed by using radio-frequency/microwave software which is named ADS on the basis of theoretical calculations and analysis, four additional transmission zeros are imported beyond the pass-band, which can effectively suppress the frequency interference near the zero points, and improve the anti-jamming capability of the communication system. The results of RF high-pass filter show the voltage standing wave ratio is less than 1.5, and the insertion loss is less than 0.5 dB within its pass band. Its inhibition is greater than 25 dB between DC and 650 MHz. Compared the difference between the theoretical design and the design by using simulation software, it show the theoretical calculation is tedious and complex, and use the simulation software to design is simple, high efifcient, fast and convenient to tune. The method can be used to design other RF iflter.关键词
