Attenuators are important electronic components that are widely used in various electronic devices, especially in communications, instruments and equipment, and test systems. They are mainly used to adjust the size of the signal in the circuit, prevent signal overload, protect instruments and equipment, optimize signal transmission, and improve impedance matching. Attenuators are divided into two ...

In high-frequency electronic systems like wireless communications, radar systems, and medical devices, RF filters (Radio Frequency Filters) act as "traffic controllers" for signals. These critical components precisely screen specific frequency ranges, ensuring optimal device performance. This article breaks down the core technology behind RF filters and addresses key selection criteria e...

What Is an RF Filter? An RF filter is a passive or active component that allows signals within a certain frequency range to pass while attenuating signals outside that range. Filters are essential in both transmit and receive chains to isolate specific frequencies and prevent crosstalk, interference, or signal distortion. Types of Filters by Frequency Selection Depending on the application, filter...
