• HMC1122 issue

    hi 

    this is the block diagram of HMC1122, when I was testing this IC using multimeter 

    I found that:

    1. pin 5 and pin 6 are connected with package base GND.

    2. pin 7,8 to pin 12 are connected together with pin 6 and pin 13 in DC.

    3. pin 7,8 to pin…

  • HMC1122 switching control frequency

    HMC1122 digital step attenuator - settling time is 250ns. I would like to know switching control frequency - the max rate at which attenuator control word can be given.

  • Should I pull down HMC1122 digital port or let them float when it is in parallel mode?

    In datasheet, it says we should pull down or D0-D5 when it is in serial mode. But what about digital port in parallel mode? Should we let them float or pull them low. Thanks.
