1500 Watt Series
RF Coaxial Terminations
1500 Watt Convection-Cooled/ Air-Cooled RF Terminations are a valuable and reliable accessory for reducing power levels, for isolating components under test, for harmonic signal analysis, and as comparison standards. They are world renowned for their high-quality, robust construction and conservative power ratings.
Convection cooling describes a termination equipped witha heat-sink with cooling fins which increases the effective heat exchange toward the environment. The heat sink is characterized by its thermal resistance or by the increase of surface temperature per watt (in °C per W). The shorter this value is , the greater the power will be.
Air-cooled loads use the properties of moving air to transfer the heat away from the resistive element. Typically, these terminations are equipped with fans to move the air past the resistors. They are virtually maintenance free, handle extremely high peak powers and high operating temparatures. They do have a large footprint which also limits the frequency.
