[Abstract]:Whether military or civilian products, as the key system of wireless communication and electronic reconnaissance. Part of the broadband amplifier more and more national attention, the performance of the whole wireless communication system depends directly on it. This paper has a four power on channel microwave and millimeter wave broadband power amplifier module, including L band (1.2GHz) channel, S, C, X band (2-18GHz) channel, K channel and K band (20.2GHz), Ka band (22-40GHz) channel. The specific works are as follows: 1. on the microwave amplification technology of millimeter wave broadband background and significance of the research are briefly introduced, and lists in the microwave and millimeter wave broadband amplification.2. developments in the field at home and abroad are briefly introduced. The basic theoretical knowledge, including the types and uses of amplifier amplifier, amplifier basic structure and main technology of microwave and millimeter wave amplifier The index, the technical indicators to provide theoretical support for the design of.3. next to the microwave and millimeter wave broadband power amplifier module of the first detailed analysis of the microwave and millimeter wave broadband power amplifier module, then according to the technical requirements, each of the four channels: 2-18GHz broadband power amplifier channel, 1.2GHz frequency power amplifier channel. 22-40GHz broadband power divider preliminary design amplifier amplification channel and 20.2GHz channel frequency power, and the design principle of a detailed analysis of.4. using Ansoft HFSS simulation software used to design the source device - power splitter is simulated, including: 22-40GHz channel power divider, 20.2GHz and 2-18GHz channel. Is.5. with the preliminary design scheme of monolithic device selection, and on the part of the monolithic device (such as HMC463, CHA2097a etc.) were designed and manufactured for the separate test verification module Based on the testing results, completed the final design. Then combined with the final design to complete the design work of other topologies, including the design of bias circuit and detection circuit of 2-18GHz channel and 1.2GHz channel power amplifying link, design of bias circuit and detection circuit of 22-40GHz channel and 20.2GHz channel power amplifying link and the microwave and millimeter wave broadband power amplifier module circuit design comparison of two.6. modules were tested, and the test results are analyzed. After the test is completed, 2-18GHz channel and 1.2GHz channel power amplifying link unit module, the comparison circuit of 22-40GHz channel and 20.2GHz channel power amplifying link unit module and the broadband microwave and millimeter wave power amplifier module assembly, finally completed the main work of the whole system of the normalized power supply of the.7. In this paper, the shortcomings are pointed out, and the future work prospect is put forward.
