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...

Typical Applications of Combiners in Macro Sites and Indoor DAS Systems
Aug , 27 2025
In modern mobile communication networks, especially during the deployment of 4G LTE and 5G NR, the number of frequency bands and systems continues to increase. To reduce the complexity of the antenna-feeder system and improve network deployment efficiency, the combiner has become an essential passive component in both macro base stations (macro sites) and Distributed Antenna Systems (DAS). Proper ...
