What Does a Mismatched Coupled Port Actually Affect in a Directional Coupler?
Jul , 23 2025
Directional couplers are widely used in RF systems for signal sampling, power monitoring, VSWR detection, and PIM testing. While these components are passive by nature, their performance is highly dependent on how each port is terminated—especially the coupled port. In real-world applications, improper termination of the coupled port—either by leaving it open, using poorly matched devices, or low-...

Passive Component Bottlenecks and Solutions in Operator Networks
Sep , 03 2025
In operator network deployment, passive components play a crucial role in ensuring stable and efficient RF signal transmission. With the rapid evolution of 5G, DAS (Distributed Antenna Systems), and private networks, the performance requirements for passive devices have become more stringent. However, components such as power splitters, couplers, and combiners often encounter performance bottlenec...

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...
