Hi All,
I am using a broadband 6-bit digital attenuator MMIC from www.astramtl.com
Its a very good chip, but sometimes, I get ripple in the attenuation states... particularly in last 15-20 states. And by the time all 6 bits are switched on, the ripple goes to almost 3 dB.
This chip has an on-chip TTL driver, so there is not much I can do about the control to different attenuation states.
Can someone help please.
Regards,
VAgarwal
