Utilizing special materials and structural designs, they can operate stably in high-frequency environments, effectively absorbing signal energy and protecting circuits and equipment. However, currently, the internal structure of high-frequency loads is fixed, and due to variations in production batches and materials, their components cannot be fine-tuned after molding, significantly impacting high-frequency signal absorption performance.
