Three operating modes are dual-band filtering balun operating at 1.43 GHz and 1.76 GHz, low-band filtering balun centering at 1.43 GHz for WMTS application, and high-band filtering balun working at 1.76 GHz for wireless communication. Three operating modes can be independently switched by controlling the voltages of PIN diodes loading at the open-ended of dual-mode resonator. The dual-band bandpass filtering responses are achieved by embedding two pairs of dual-mode resonators. The simulated result shows good performance.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116686552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MATLAB has the advantage in data analysis and processing, and it integrates matrix calculation, numerical analysis, scientific data visualization, modeling and simulation of nonlinear dynamic systems and some other powerful functions in an easy-to-use windows environment so that it can provide a comprehensive solution for scientific research, engineering design, and some other fields. Accordingly, a simulation method of 16QAM modulation and demodulation based on MATLAB is proposed, which can simulate the 16QAM modulation and demodulation of the randomly-chosen signal as well as get the simulation image by compiling and running the matlab program. This method can reflect the change of parameters as well as the dynamic working process of modulation and demodulation, and it can also perform the data process, waveform, and performance analysis of the image obtained in the end, which has the advantage of intuition and clarity.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134179494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The theoretical analysis and results of simulation show that the model has better self-similarity.

Finally, a multi-transmission zero bandpass filter is designed by simulation. The simulation results shows the effectiveness of the design method.
