    High Power Waveguide Terminations

    A high-power waveguide termination is a passive component used to absorb high-power microwave signals, typically in the power range of over 1 kilowatt. They are similar to medium power waveguide terminations and low power waveguide terminations, and are used to protect the operation of other components in microwave systems, avoid signal reflection, and improve the matching and stability of the system.

    Under high-frequency operating conditions, high-power coaxial terminations can no longer meet the requirements of the system, so high-power waveguide terminations are introduced to withstand an average power greater than 60W. This is because high-power waveguides are composed of waveguides, high-temperature absorbing materials, and heat sinks. The heat generated in high-frequency and high-power microwave systems can be transferred to the air through the waveguide termination, thus maintaining normal operation and achieving low standing wave and stable electrical characteristics.

    Its characteristics are as follows:

    1. High power carrying capacity: High power waveguide terminations can withstand high-power microwave and millimeter wave signals, typically reaching a power range of several thousand watts to tens of kilowatts.
    2. Low reflection loss: The design of high-power waveguide terminations is reasonable, which can effectively reduce the reflection loss of signals and improve the accuracy of testing.
    3. High temperature resistance: Due to the need to withstand the heating effect of high-power signals, high-power waveguide terminations are usually designed with special materials and structures to have excellent high temperature resistance.
    4. Broadband characteristics: High power waveguide terminations can operate over a wide frequency range, suitable for testing various high-power microwave and millimeter wave signals at different frequencies.

    In practical applications, high-power waveguide terminations are commonly used for calibration of laboratory microwave systems, testing of antenna radiation power and radiation mode, control of high-power signals in radar and communication systems, microwave heating and plasma discharge, and other fields. They are suitable for assisting in high-power system testing, tuning, and maintenance.

    Qualwave provide broadband and high-power waveguide terminations, covering a frequency range of 2.17~59.6GHz. The average power handling is up to 2500 watts. The terminations are widely used in many applications.
