Research And Design Of 8mm Band Hybrid Integrated Up-converter Module

The Radio Frequency Simulation System(RFSS)plays an irreplaceable role in precision-guided missile weapon system.With the development of millimeter wave seeker,the millimeter-wave RFSS came in to being.In the millimeter-wave RFSS,the up-converter module is a key component,which has an important impact on the system performance.Therefore,the performance of the up-converter module is of great practical significance.In order to meet the requirements of an actual RFSS,in this dissertation,an 8mm band hybrid integrated up-converter is studied and designed.The main contributions are as follows.1.According to the specifications of the up-converter,the module scheme is designed.The key active components used in the scheme include a HMC560 mixer chip,an AMMC-5040 millimeter-wave amplifier and an AMMC-6345 power amplifier.The parameters of the passive components utilized are specified.2.The design and simulation of the passive components including an IF frequency miniaturized wideband BPF,an IF amplitude equalizer and a millimeter-wave BPF of the system are completed.The passive components are individually fabricated and measured to verify the design.3.Based on the above mentioned works,the microwave planar circuit,the voltage supply circuit and the shielding cavity are designed respectively.Finally,the up-converter module is fabricated based on Microassembly technology.Measurement results show that,within the working band from 34 to 36 GHz,the module is able to meet the specifications of gain greater than 38 dB,output power greater 23 dBm,and spur suppression greater than 40 dBc.
