2450±50MHz, 15KW Waveguide Water-Cooled Load, 55dB Coupling

A high-power waveguide load is a device with a terminal at the end of a waveguide (a metal tube used for transmitting high-frequency microwave signals) or coaxial cable. It can absorb and dissipate almost all incoming microwave energy with minimal reflection, converting it into thermal energy. It serves as an indispensable key component in ensuring the safe, stable, and reliable operation of the entire high-power microwave system.

Characteristics:

1. Ultra high power, stable and reliable: With a power capacity of 15KW combined with water-cooled heat dissipation, it can dissipate huge energy stably for a long time, providing the ultimate protection for the system like a rock, ensuring the safety of high-value core components, and improving the system's lifespan and reliability.
2. Accurate monitoring and intelligent control: Integrated with a 55dB high directional coupler, it can monitor the system power status in real-time and accurately with extremely low interference like a "precision instrument". This provides key data for process optimization, fault diagnosis, and closed-loop control, endowing the system with "intelligence".
3. Integrated, optimal performance: The high-power load and high-precision coupler are designed to be integrated, simplifying the system structure and ensuring monitoring accuracy. It has been optimized for the commonly used industrial and medical frequency band of 2450MHz, with excellent performance in this frequency band, surpassing discrete solutions.

Applications:

1. In the field of industrial heating and plasma: In large microwave heating equipment and plasma excitation devices (such as etching and coating equipment in semiconductor processes), it is the core protection unit and monitoring unit that ensures stable power source output and prevents energy reflection damage.
2. Scientific research and particle accelerators: In high-power radar and particle collider RF systems, such loads are required to absorb the enormous energy generated when the beam is mismatched, protect the acceleration cavity and power source, and use couplers for precise beam feedback control.
3. Medical equipment: In high-power medical linear accelerators (used for cancer radiation therapy), it also plays a key role in energy absorption and system protection, ensuring the safety and accuracy of the treatment process.
4. System testing and debugging: In research and production lines, it can be used as an ideal dummy load for full power aging testing and performance verification of high-power microwave sources, amplifiers, etc.
