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,

    Thank you for your answer. Yes, I'll advise to the customer getting the evaluation board of HMC773A and testing it.

    By the way, according to the customer, he has used HMC412AMS8GE and HMC292LM3C by swapping the ports before. HMC412, HMC292 and HMC773A are passive double balanced mixer. Are there any changes of circuit structure between HMC412, HMC292 and HMC773A?

    Thanks & Regards,
