Common waveguide components: waveguide terminals
Mar , 18 2025
2. Waveguide Terminals 2.1 Performance Characteristics Key electrical parameters include frequency range (determined by waveguide dimensions), VSWR, and input power handling. Physical attributes like size, weight, and material selection (e.g., corrosion-resistant plating) are equally vital. Thermal management strategies vary: 2.2 Materials and Applications A waveguide terminal typically consists o...

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 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 ...
