HMC773A: Can we swap LO/IF port?

Hello,

Can we use HMC773A by swapping LO/IF port under following condition?

For RX;

  Input RF signal : 18.5GHz, maximum 0dBm

  Input LO signal : 0.5GHz, +13dBm

  IF = 18GHz

For TX;

Input IF signal : 18GHz, maximum 0dBm

Input LO signal : 0.5GHz, +13dBm

RF = 18.5GHz

We understand it is not recommended use and you do not guarantee performance. But, could you please advide us we can do like that use? And what kind of impact to perfomances of HMC773A?

Best regards,

Akira

    Hi Akira,

     

    HMC412, HMC292 and HMC773A are passive balanced mixers. To make the parts work properly, all the ports need to be fed within frequency range as data sheet required. Otherwise large portion of signals might be reflected.

     

    By the way, HMC412AMS8GE and HMC292LM3C are not recommended for new designs. A new part can be recommended if needed.

     

    Thanks,
