1. Digitally programmable attenuators are used to adjust signal levels in communication systems. They employ digital programmable technology to achieve signal level adjustment within the DC4G broadband frequency range. 2. By utilizing a CNC housing design, it provides electromagnetic shielding and can be cascaded with other modules. 3. When using parallel control, the control interface is reserved and can be connected to an external mechanical switch or an external MCU controller. The attenuation step is 0.5 dB, enabling broadband attenuation adjustment from 0.5 to 31.5 dB. 4. Advanced RF Control: This digitally programmable attenuator offers precise signal modulation from DC to 4 GHz and is suitable for various RF applications. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
