What is an RF load used for?

RF Loads convert RF electrical energy into heat, allowing it to be dissipated efficiently, economically, and safely. Often referred to as "dummy loads" or terminations, their primary purpose is to absorb RF energy without radiating it. They are commonly used in place of antennas during transmitter testing to simulate real operating conditions without generating radio waves.

Use the following criteria when selecting a load:

• Frequency range - the operating frequency range of each dummy load
• Maximum VSWR - measure of how well the load is "matched" to the transmission line
• Peak to average power ratio - how much "instantaneous" power can be absorbed
• Power rating - the amount of heat a load can absorb
• Mechanical considerations - connector gender and type, dimensions, coolant type
• Environmental considerations - ambient temperature range, coolant flow and temp, humidity, altitude
