Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to a balun line rapid bending and forming fixture. Background Art

[0002] As one of the core technologies of the third scientific and technological revolution, wireless communication technology has ushered in rapid development in recent years with the continuous investment of academia and industry, and has continuously provided production and life with ultra-high capacity, ultra-low latency, large connections, high reliability and other ultimate experiences. One of the main challenges in communication system design is how to capture signals with sufficient signal-to-noise ratio. Strict standards and specifications have put forward new requirements for the system. For example, code division multiple access (CDMA) and frequency division multiple access (FDMA) require high dynamic range, high input linearity and low noise to avoid blocking, signal distortion and sensitivity reduction. In the past, due to factors such as process device power consumption, the performance advantages of fully differential signal chains were replaced by single-ended signal chains. However, with the upgrading of manufacturing processes and innovations in circuit design, differential architectures have been applied to RF system design.

[0003] As an important component that converts differential signals into single-ended signals or single-ended signals into differential signals, balun cables are widely used in various radio frequency and communication systems. They not only improve the efficiency and quality of signal transmission, but also provide guarantees for the stability and reliability of the system. In practical applications, the design and implementation of balun cables must take into account many factors. In order to meet the requirements of overall miniaturization of microwave devices, balun cables need to be bent into different shapes and sizes to reduce the size of the overall device. According to circuit design requirements, coaxial balun cables usually need to be bent into specific shapes before they can be applied to actual products. The current manual bending method is not only inefficient, but also has poor bending quality and is difficult to ensure consistency. Utility Model Content

When the upper mold of the bending mold is fitted with the lower mold of the bending mold, the second molding surface is fitted with the step surface.
