  • Operating frequency: DC-2.5 GHz
  • Connector style: SMA-K-K(SMA) / N-K-K(N). Select the connector model you need.
  • Rated power is 3-10 watts, there are 4 models in total, namely 2W, 5W, 8W, 10W, you can choose the power model you need
  • The key-adjustable attenuator can adjust the signal level of the circuit in 1dB steps without interrupting the circuit. It can also be used as an in-machine attenuator for instruments and equipment to adjust the power level in the test system. It has a small size, high precision, stable and reliable characteristics.


Manually variable step attenuators are used in a wide variety of applications and can satisfy almost any requirement where a reduction in power is needed. Attenuators are used to extend the dynamic range of devices such as power meters and amplifiers, reduce signal levels to detectors, match circuits and are used daily in lab applications to aid in product design. Attenuators are also used to balance out transmission lines that otherwise would have unequal signal levels.
