Description

Technical Field

[0001] The invention relates to the technical field of filters, and in particular to a structure for hoisting and enhancing capacitive coupling. Background Art

[0002] A filter is an electronic circuit or system that processes signals by allowing certain frequencies to pass through while suppressing or reducing other frequencies. Filters are widely used in electronic engineering, signal processing, communications, audio systems and other fields to improve signal quality and remove noise or interference. Filters play an important role in modern electronic systems, and their design and implementation depend on specific application needs and performance requirements.

[0003] In filter design, due to strict index requirements and relatively high frequency, the total length of the capacitor copper sheet cannot be too long. If the total length is too long, the frequency and harmonics generated by the copper sheet itself will affect its own passband, thereby failing to meet customer specifications. In previous designs, dumbbell-shaped capacitors were used to avoid the problem of the total length of the copper sheet being too long, but the dumbbell solution is more sensitive, difficult to adjust, and has high cost for special parts processing; it is not the preferred alternative. In view of this, the present invention is proposed. Summary of the invention
