Abstract

The embodiment of the invention discloses a high-frequency patch resistor which comprises a substrate, a back electrode, a surface electrode, a resistor body and a first lateral conducting electrode, wherein in order to enable characteristic impedance to be matched with anticipatory target impedance, the resistor body is provided with an external cutting notch, i.e. cutting is started from the edge of the resistor body, the partial area of the resistor body is directly cut off from the resistor body, and the cross-sectional area of the resistor body can be decreased to a greater degree, so that the high-frequency patch resistor has a larger resistance-adjusting range and is beneficial to the matching of the characteristic impedance of the characteristic impedance resistor and the anticipatory target impedance. The invention also provides a manufacturing method of the high-frequency patch resistor to manufacture the high-frequency patch resistor with the larger resistance-adjusting range. The high-frequency patch resistor provided by the invention is suitable for microwave radio-frequency structures and chipping, and meanwhile, the high-frequency patch resistor can be manufactured in large scales and with high efficiency by utilizing the manufacturing method of the high-frequency patch resistor provided by the invention.

Description

technical field

[0001] The present invention relates to the technical field of resistors, more specifically, to a high-frequency resistor and a manufacturing method thereof. Background technique

[0002] Chip resistors, also known as chip-type fixed resistors, generally have the characteristics of moisture resistance, high temperature resistance, high reliability, uniform dimensions, and are suitable for surface mount technology (SMT for short). Because it can greatly reduce the size of the product, chip resistors have been widely used in various electrical appliances. High-frequency chip resistors are a type of basic electronic components used in microwave high-frequency communication circuit components.

[0003] In the manufacturing process of high-frequency resistors, the initial impedance of the resistor is generally lower than the target impedance. In order to make the characteristic impedance of the high-frequency resistor reach the expected target impedance value, ac...
