How is Insertion Loss Generated in High Power Couplers

Insertion Loss Analysis: High Power Coupler

Identifying and addressing key factors affecting transmission efficiency in high-power applications

1 Energy Loss Caused by Medium Characteristics

  • The inherent characteristics of the core transmission medium are a significant factor in High Power Coupler insertion loss.
  • Different media have different conductivity and insulation properties. When energy is transmitted through the medium, some energy is converted into heat energy due to the resistive effect of the medium.
  • Meanwhile, polarization loss and dielectric loss of the medium also lead to energy loss, especially in high-frequency operating scenarios.
  • Rapid polarization of medium molecules exacerbates energy loss, thus affecting the High Power Coupler's transmission efficiency.

2 Optimization Space in Structural Design

  • The structural design of the High Power Coupler directly affects the energy transmission path and efficiency.
  • If the signal transmission path is poorly designed, energy will scatter and reflect during transmission, and untransmitted energy will be converted into losses.
  • Furthermore, unreasonable corners or cross-sectional changes in the structural layout can cause abrupt changes in energy transmission direction, leading to localized energy concentration and loss.
  • Additionally, if the coupling degree design of the coupling structure does not match actual requirements, some energy will not be effectively coupled, resulting in insertion loss.

3 Contact Losses Due to Assembly Processes

  • Insufficient process precision during assembly can cause contact losses in High Power Coupler systems.
  • If the interfaces are not tightly fitted during component assembly, tiny gaps will form, leading to leakage and energy loss during transmission.
  • Furthermore, misalignment or insecure fixing of components during assembly can cause signal transmission path deviation, exacerbating energy scattering and reflection.
  • Meanwhile, impurities or contaminants introduced during assembly can affect the conductivity of the contact surfaces, further increasing insertion loss.

4 Indirect Impacts of the External Environment

  • External environmental factors can indirectly exacerbate insertion loss in High Power Coupler applications.
  • Temperature changes in the environment affect the performance of core components, causing fluctuations in dielectric properties and circuit parameters, thereby affecting energy transfer efficiency and generating additional losses.
  • High humidity environments can cause moisture to accumulate on component surfaces, affecting insulation and conductivity and leading to energy leakage.
  • Furthermore, external electromagnetic interference can disrupt the stability of energy transfer, causing some energy to be consumed by interference signals, indirectly increasing insertion loss.
