Design of a high sensitivity multi beam four channel transceiver module

The phased array radar system has become the development trend. In order to replace the early single function equipment transceiver radar system, the multi-function integrated design is adopted to effectively improve the sensitivity of the receiver and the anti-interference ability of the adjacent channel. This paper introduces the design of an X-band four channel transceiver module, which uses the secondary IF superheterodyne frequency conversion to realize the spectrum shift, and uses the module stacking technology to realize the miniaturization design. The simulation software Genesys is used to analyze the link spurious, and HFSS software is used to design the long vertical transition. Finally, the multi beam receiver module with sensitivity less than -105dbm, amplitude consistency less than±0.5dB and phase consistency less than±6°is completed.
