The Design Of Multiplier Components With Ultra-wideband And Multi-channel

The main work of this paper is to design an ultra-wideband multi-channel frequency multiplier component with input signal frequency of 2 GHz to 4 GHz,input power of 0 dBm,output frequency of 4 GHz to 16 GHz,output power of 13 dBm,Eight output.According to the project,we want to divide each output signal into four bands,namely 4 GHz-5.6 GHz;5.6 GHz-8 GHz;8 GHz-11.2 GHz;11.2 GHz-16 GHz,and output via logic switch control Band switching.In the field of communication,broadband communication has very important significance.At the beginning of this paper,the development of broadband system components and related fields is introduced,and the research background and significance of this paper are clarified.Through the analysis of the system index,we elaborated in the second chapter of this article on the system design ideas and processes,from the overall grasp of the composition of the system,and clear the entire system work required for several key modules.And the whole system of the index analysis,clear the corresponding indicators of each module to guide the follow-up module design.Chapter 3 deals specifically with the design of each module in the system.Mainly include switching filter components,amplification equalization components,power sub-amplification components.We have four filter designs in the switch filter module.The filter is unified with the cross-talk structure and modeled and simulated by Ansoft's HFSS simulation software.According to the simulation results,we processed a 4 GHz-5.6 GHz filter and compared the test results with the simulation results.In the design of the amplification equalization component,we use the circuit simulation software ADS,combined with the amplifier s2 p file provided by the S-parameter curve to the equalizer design.Equalizer structure using three-level resistance loading,this structure has a small size,fast design and so on.From the measured results,the equalizer has a 1.5 dB amplitude equalization in the 4 GHz-16 GHz operating band,which is slightly different from the simulation results.Due to the need for balanced amplification components,we have also designed the amplifier bias circuit and power supply protection circuit to ensure the safety and stability of the amplifier operation.In the design of the power amplifier module,we mainly completed the design of a fourth order Wilkinson power splitter.The insertion loss of the power splitter in the entire operating frequency band does not exceed 0.5 dB,the return loss is greater than 15 dB,and the isolation can reach more than 20 dB.The fourth chapter mainly uses the actual measurement and simulation results of each module to simulate the whole system.Simulation results show that the feasibility of the scheme is verified by the simulation results.In order to follow the test work,we first carried out does not contain the power of the magnification module layout design.The fifth chapter is the summary and prospect part,summed up the work of the paper,found out the mistakes and shortcomings in the work and corrected,and made a plan for the next work of this paper.
