Digital Step Attenuators

Highly accurate 50Ω digital step attenuator model providing adjustable attenuation from 0 up to 31.75dB in 0.5 or 0.25 dB steps.

 

The control interface supports a 6bit or 7bit serial interface with 3-bit addressable function and latched parallel interface. It is also supporting a broad operating frequency range from 1MHz to 6.0GHZ or 8.0 GHz. The device features a safe state transitions with no negative/positive Glitch technology optimized for excellent step accuracy. The design is bi-directional; Therefore, the RF input and output are interchangeable and in addition this series does not require blocking capacitors to minimize PCB space.
