Design of RF Micro-system Based on Multi-chip Stacking

With the continuous development of miniaturization of electronic equipment, the research and development of radio frequency micro-system has become increasingly popular. Multi-chip stacking is one of the key technologies of RF micro-system. The selection of stack structure will have a significant impact on the performance of the system. According to the requirements of RF micro-system, two kinds of chip-stack structures are adopted, and the stack structure is simulated and optimized. A frequency conversion channel is designed based on the chip-stack structures, which realizes the functions of amplification, mixing, amplitude control, power division and detection of 2–6 GHz RF signals. The key technology analysis and simulation of the system are carried out. The results show that the RF micro-system has the characteristics of small size, high integration and excellent RF performance.
