Key Technologies Research On 3mm Miniaturized Multi-channel Transceiver Module

Millimeter wave is widely used in various fields of military and civilian applications because of its high frequency,narrow beam,large absolute bandwidth with the same relative bandwidth,and easy miniaturization and integration of circuits.As one of the bands containing atmospheric windows,W-band is a key band for modern military electronics and modern communication technology,and is widely used in radar,electronic countermeasures and precision guidance.With the increasing miniaturization requirements of electronic systems and the advancement of related advanced electronic packaging technologies,it is important to conduct Si P research on transceiver systems with higher integration in the three millimeter bands.In this thesis,the design of the transceiver component working mode is based on the working principle of sum-difference beam antenna,and finally the working mode of single channel transmitting and 4 channels receiving is adopted.In this thesis,a three-dimensional miniaturized multichannel transceiver module operating in the three-millimeter band is designed and tested using hybrid integration technology,and the passive devices such as parallel line directional coupler,one-in-two Wilkinson power divider and substrate integrated waveguide inductive window bandpass filter are designed independently with the module.Based on the hybrid integration process of structural components,a three-dimensional integrated three-millimeter miniaturized multi-channel transceiver module is proposed,with the size Φ39mm×8mm.In addition,on the basis of the same index,a variety of horizontal and vertical transmission interconnection structures based on the high-temperature co-fired ceramic process are simulated to verify the feasibility of designing a three-millimeter band transceiver module based on the high-temperature co-fired ceramic process,and the transceiver module is redesigned and a new scheme is proposed based on the process.
