Dummy Loads for frequencies up to 3 GHz

The purpose of a Dummy Load (also known as a Termination Load) is to absorb RF energy and convert it into heat. The dummy load takes the place of an antenna during transmitter testing and adjustment.

Other applications where dummy loads are used include hybrid couplers, isolators, circulators, system testing and calibration.

The load must be selected to match the antenna and transmission line impedance; typically 50 Ohms. Also the load needs to be designed to tolerate the amount of power that can be delivered by the transmitter.

This selection of 50 Ohm Dummy Loads with N-Male connector are rated for frequencies up to 3 GHz. They use parallel ceramic resistors to dissipate heat while power is applied.

8258 is rated for 5 watts maximum power.
8259 can handle 25 watts power.
8260 is our largest dummy load for up to 60 watts power.
