Improving Passive Component Performance in DAS Networks
Jul , 31 2025
1. Introduction: The Role of Passive Components in DAS Distributed Antenna Systems (DAS) play a vital role in enhancing wireless coverage in complex environments like airports, stadiums, hospitals, and office buildings. While active equipment such as base stations and repeaters often receive the most attention, passive components—such as power splitters, directional couplers, loads, tappers, and h...

How to Avoid PIM Interference in DAS Systems
Aug , 07 2025
In Distributed Antenna Systems (DAS), Passive Intermodulation (PIM) is one of the most common yet overlooked causes of performance degradation. While DAS networks are designed to enhance wireless coverage and capacity, PIM can severely compromise signal quality, leading to dropped calls, reduced data throughput, and costly troubleshooting. This article outlines the practical measures and engineeri...

Mastering Power Splitter Design: From Principle to Engineering Practice
Oct , 11 2025
In RF and microwave systems, the power splitter is a core passive component responsible for dividing an input signal into multiple outputs with minimal loss and perfect impedance balance. From cellular base stations to satellite networks and RF test systems, the power splitter ensures signal integrity across transmission paths. 1. Basic Principle of Power Splitters A power splitter divides an inpu...
