Coaxial Termination

Coaxial loads are assembled with connectors, heat sinks, and resistive chips in single or multi-chip configurations. Connector types include 2.92mm, SMA, N, DIN, and 4.3-10, while heat sink dimensions scale with power handling. They absorb RF/microwave power as dummy loads for antennas and transmitters, or as matching terminations on unused ports to prevent signal reflections during testing. With wide operating bandwidth, low VSWR, high power capability, compact size, and high burnout resistance, our coaxial loads reach a maximum frequency of 110 GHz.

Coaxial loads are assembled from connectors, heat sinks, and internal resistive chips. Depending on different frequency and power requirements, common connector types include 2.92, SMA, N, DIN, 4.3-10, etc. Heat sinks are designed with corresponding dimensions according to the cooling requirements of different power ratings. The internal resistive chips use either a single chip or a multi-chip configuration based on specific frequency and power specifications.

They are primarily used to absorb power in RF or microwave systems, or act as dummy loads for antennas and transmitter terminations. In some RF tests, to avoid signal reflections that could affect measurement results, they are connected to unused ports as matching loads to absorb port energy. They can also serve as dummy loads when evaluating system performance with simulated terminations (e.g., antennas).
