Research On Microwave And Milliter Wave Broadband Splitter & Amplifier Module

Whether the military or civilian products, as a wireless communication system, one of the key components of broadband amplifiers more and more national attention, good or bad performance of the entire wireless communication system depends directly on it.In this paper, a microwave and millimeter wave with a four-channel wideband power amplifier module, including L-band(1.2GHz) channels, S&C&X-band(2-18GHz) channels, K-band(20.2GHz) channels, and K&Ka-band(22-40GHz) channel. Specific work as follows:1. Research the background and significance of the microwave and millimeter wave broadband amplification techniques are briefly introduced, and cited in the field of microwave and millimeter wave broadband amplification’s domestic and foreign development Situation.2. Details of the basic theoretical knowledge of the amplifier, comprising: an amplifier of the type and purpose of the basic structure of the amplifier and the microwave and millimeter wave amplifier major technical indicators, designed to power the next points of microwave and millimeter wave broadband amplifier module is to provide the theoretical stand by.3. First, a detailed analysis of microwave and millimeter wave broadband power dividers amplifier module various technical indicators, and according to the technical indicators, respectively, four channels: 2-18 GHz broadband power dividers amplification channel, 1.2GHz frequency splitters point amplification channel, 22-40 GHz broadband power dividers amplification channel and 20.2GHz frequency splitters point amplification channel presented a preliminary design, and design principles are analyzed in detail.4. Use Ansoft HFSS simulation software for passive components used in the design- power splitter simulation, including: 22-40 GHz channel splitters, 20.2GHz and 2-18 GHz channel splitters.5. The combination of preliminary design monolithic device selection, and the choice of each single device, such as HMC463, CHA2097 a design and processing, respectively, the test chamber, individually tested and the test results on the final design is completed. Then combined with the final design of other circuit topology design is complete, including 2-18 GHz channel and 1.2GHz channel splitters amplification chain’s bias circuit and a detection circuit design, 22-40 GHz and 20.2GHz channel splitters amplification chain’s bias circuit and a detection circuit, and the whole design of comparator circuit.6. Two cell modules were tested, and the test results were analyzed. After the testing is completed, the 2-18 GHz channel and 1.2GHz channel splitters amplification chain unit module, 22-40 GHz channel and 20.2GHz channel splitters amplification chain unit module and the entire microwave and millimeter wave broadband splitters amplification module’s comparator circuit were fitted with the outer cavity. Finally, the work to overall power supply was completed.7. The main work of this paper summarizes, pointing out shortcomings and proposed future work prospects.
