Terminators, also known as loads or dummy loads, are used to dissipate RF energy without radiating electromagnetically. They are used to cap-off unused ports on couplers and dividers, maintaining the device’s impedance and VSWR specification.

The load value, in this case 25 Watts, defines the maximum amount of energy capable of being dissipated. RF energy is dissipated through thermal radiation, i.e., heat, and consequently large loads require heat-sink features.

This N Male load is suitable for terminating couplers and dividers that have an N Female port interface.
