AI Technical Summary

Technical Problem

Existing RF switches or RF switch chips are large in size due to electromagnetic compatibility issues, which makes them unsuitable for high-density integration and causes energy loss, affecting performance.

Method used

Inductance pairs formed by two inductors are used and arranged in adjacent positions with opposite directions of the induced magnetic field to reduce mutual coupling, reduce energy loss and reduce chip area.

Benefits of technology

This achieves a compact layout for the RF switch circuit, reducing chip area and cost while minimizing energy loss and improving performance.
