RFTYT Microwave Attenuators Broadband Microwave Attenuator

Microwave attenuation chip is a device that plays a role in signal attenuation within the microwave frequency band. Making it into a fixed attenuator is widely used in fields such as microwave communication, radar systems, satellite communication, etc., providing controllable signal attenuation function for circuits.

Microwave attenuation chips, unlike the commonly used patch attenuation chips, need to be assembled into a specific size air hood using coaxial connection to achieve signal attenuation from input to output.

Overview

The working principle of microwave attenuation chips 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 microwave attenuation chips 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 microwave attenuation chip 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.
