High-power attenuators are used as dummy loads for transmitters and amplifiers in the frequency range 0 Hz to 6 GHz. Their constant attenuation enables harmonics measurements on transmitters, TV transposers and other equipment.
The high-power attenuator is superior to a simple termination. The power applied can be accurately determined from the power measured at the test output and from the known attenuation. Moreover, a frequency counter or analyzer can be connected to the test output.
The R&S RBU high-power attenuators with 3/6/10/20/30 dB attenuation are ideal for applications in the frequency range up to 2 GHz, which is of particular interest for mobile radio measurements. The attenuators are characterized by low VSWR and low attenuation error throughout the entire frequency range. Due to the large heat sink, the attenuator surface temperature does not rise above +75°C (at +25°C ambient temperature) even under full load.
