5G-Advanced Accelerates New Requirements for In-building RF Infrastructure
Apr , 28 2025
As 5G-Advanced (5G-A) technology emerges, it brings higher speeds, lower latency, and smarter network capabilities, reshaping expectations for in-building wireless systems. Modern facilities—such as offices, airports, and hospitals—now require more advanced Distributed Antenna Systems (DAS) capable of supporting higher frequency bands and broader bandwidths. Traditional infrastructure must evolve....

Which Is Better: Directional Coupler or Tapper?
May , 08 2025
In RF and microwave systems, power distribution is a critical aspect that directly impacts system performance, reliability, and design flexibility. Two of the most commonly used passive components for signal splitting and power monitoring are directional couplers and tappers. While they serve similar purposes in many systems, they differ significantly in structure, application, and performance. Un...

Difference Between UHF and VHF Antenna: Choosing the Right Frequency for Your Application
May , 28 2025
What Is a VHF Antenna? VHF antennas operate within the Very High Frequency range of 30 MHz to 300 MHz. These antennas are commonly used in: FM radio broadcasting (88–108 MHz) Marine radio communication (156–174 MHz) Aviation communication systems Emergency and amateur radio operations Due to their longer wavelengths, VHF antennas perform well in open and rural environments where line-of-sight cove...

What Is the Input Impedance of a Log Periodic Antenna?
Jul , 12 2025
Log periodic antennas are widely used in RF communication due to their broadband capabilities. One critical aspect of their performance is input impedance, which determines how efficiently the antenna transfers power from the transmission line. Understanding this parameter is essential for engineers and hobbyists working with these antennas. Why Input Impedance Matters The input impedance o...

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-...
