Features: 1.Small and compact product 2.Stable and reliable performance 3.High precision 4.Exquisite craftsmanship 5.Display attenuation using OLED The digital attenuator can adjust the signal level of the circuit in 0.25dB steps without interrupting the circuit, and can also be used as an internal attenuator for instrument equipment to adjust the power level in the testing system. It has the characteristics of small size, high accuracy, stability and reliability, and uses OLED to display the attenuation amount, which can be controlled by the upper computer Parameters: Working frequency: LF-6GHz Attenuation adjustment range: 0-31.75dB Attenuation step: 0.25 (dB) Voltage: DC5V Insertion loss: 1.5dB (higher insertion loss at the high-frequency end) Standing wave ratio: 1.4 Attenuation accuracy: 0.25dB Max Rated power: 1W Connector type: SMA (female head, external screw and internal hole) Temperature range: -10 ~+50 (operating) -40 ~+70 (not running) Input output impedance: 50 ohms Material: PC+Metal colour: green Package Contents: 1 x DC5V Digital RF Attenuator Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
