    SMA end launch optimization

    end launch ghz Hey everyone... I am trying to get on and off a PCB at about 6GHz with the best S11 I can muster. I have been using a Johnson SMA end launch connector attaching directly to microstrip which has worked reasonably well below 3GHz. Above 4GHz this approach is probably not what I...

    Isolation cell between logic islands

    Does anyone have any good ideas regarding an isolation cell circuit for isolating two digital islands on different power domains. One of the islands will be powered down part of the time while the other remains powered up. I understand that for a powered cell driving into an unpowered domain...
