Set of 6 fixed SMA attenuators 3–40 dB, 2 W, DC–8 GHz

Product detailed description

This set of six SMA fixed attenuators with 3, 6, 10, 20, 30 and 40 dB attenuation is designed for precise RF signal level reduction in the DC–8 GHz range with an average power of up to 2 W. The attenuators protect the input of a spectrum or network analyser from excessively strong signals, assist in level setting between a generator and the circuit under test, and improve impedance matching when measuring antennas, filters and amplifiers. They feature an SMA male – SMA female design, allowing you to screw them directly into a device connector or between cables. By cascading multiple units, you can achieve additional attenuation values, such as 13 dB or 50 dB.
