Coaxial loads are mainly used to absorb power in radio frequency or microwave systems. They can serve as virtual loads for communication products and as transmitter terminations. They can also be used as matching ports for multi-port microwave devices, such as combiners and bridges, to ensure characteristic impedance. It has the characteristics of wide operating frequency, low voltage standing wave ratio, good pulse resistance and burnout resistance. Designs and production can be customized according to customer requirements.
