Overview
Microstrip attenuator is a type of attenuation chip. The so-called "spin on" is an installation structure. To use this type of attenuation chip, a circular or square air cover is required, which is located on both sides of the substrate.
The two silver layers on both sides of the substrate in the length direction do need to be grounded.
During use, our company can provide customers with air covers of different sizes and frequencies for free.
Users can process sleeves according to the size of the air cover, and the grounding groove of the sleeve should be wider than the thickness of the substrate.
Then, a conductive elastic edge is wrapped around the two grounding edges of the substrate and inserted into the sleeve.
The outer periphery of the sleeve is matched with a heat sink that matches the power.
The connectors on both sides are connected to the cavity with threads, and the connection between the connector and the rotating microstrip attenuation plate is made with an elastic pin, which is in elastic contact with the side end of the attenuation plate.
Rotary microstrip attenuator is the product with the highest frequency characteristics among all chips, and is the primary choice for making high-frequency attenuators.
The working principle of microstrip attenuator is mainly based on the physical mechanism of signal attenuation. It attenuates microwave signals during transmission in the chip by selecting appropriate materials and designing structures. Generally speaking, attenuation chips use methods such as absorption, scattering, or reflection to achieve attenuation. These mechanisms can control the attenuation and frequency response by adjusting the parameters of the chip material and structure.
The structure of microstrip attenuators usually consists of microwave transmission lines and impedance matching networks. Microwave transmission lines are channels for signal transmission, and factors such as transmission loss and return loss should be considered in design. The impedance matching network is used to ensure complete attenuation of the signal, providing a more accurate amount of attenuation.
The attenuation amount of the microstrip attenuator we provide is fixed and constant, and it has stability and reliability, which can be used in situations where frequent adjustment is not necessary. Fixed attenuators are widely used in systems such as radar, satellite communication, and microwave measurement.
