- Passwords: WYDZ
Description:
- The digital programmable attenuator is used to adjust the signal level in the transmission and reception communication system. The module adopts digital programmable control technology and 6BIT parallel control to achieve the signal size adjustment within the DC-13G ultra wideband frequency range. The module is controlled in parallel mode, with control interface reserved, and can be controlled by external mechanical switches or external MCU. The attenuation step is 0.5dB to achieve 31.5dB broadband attenuation adjustment; The module is packaged in a CNC shell, which has good electromagnetic shielding performance and can be cascaded with other modules, widely used in transmission and reception communication systems.
