Features 1.[ Adjust Signal ] Widely used in electronic equipment to adjust the size of the signal in the circuit 2.[Buffer Resistance] Improve impedance matching. If some circuits require relatively stable load impedance, an attenuator can be inserted between the circuit and the actual load impedance to buffer the impedance change 3.[Direct Read] In the comparison method measurement circuit, the attenuation value of the measured network can be read directly 4.[Resistance Stability] Uniform carbon film. Excellent electrical performance with minimum temperature change 5.[High Quality Performance] Has good uniformity and consistency, stable resistance and high reliability Specification Item Type: Digital RF Attenuator Module Material: PCB Working Frequency: DC-4.0GHz Maximum Power: 23dBm (200mW) Standing Wave Ratio: ≤ 1.20 System Impedance: 50Ω Rf Interface: SMA Double Female Head (Outer Screw Inner Hole) Attenuation Value: Straight Through: 0dB (Reference) Level 1: 10 ± 0.8dB Level 2: 20 ± 1.1dB Level 3: 30 ± 1.5dB Package List 1 x Digital RF Attenuator Module
