What Is a Coaxial Variable Attenuator and Why Is It Important?
Jun , 03 2025
In RF and microwave communication systems, precise control over signal strength is critical. A coaxial variable attenuator is a key component used to adjust the amplitude of RF signals without distorting the waveform. Whether you're testing signal paths, protecting sensitive equipment, or balancing signal levels in a network, variable attenuators offer both flexibility and accuracy. What Is a Coax...

What Is the Difference Between a Power Divider and a Power Splitter?
Jun , 18 2025
1. Basic Function — What Do They Both Do? At a high level, both power splitters and power dividers are passive RF components designed to: Take one input signal Split it into two or more output signals Maintain specific impedance (typically 50Ω or 75Ω) Preserve signal integrity as much as possible These devices are commonly used in test setups, antenna feeds, distributed antenna systems (DAS), and ...

How Do Filters Work?
Jul , 02 2025
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...
