    Hi all,
    


    We have some questions about HMC1113.
    


    1.Which Is the Lo drive input for each MIXER "0deg/0deg" or "0deg/90deg" ?
    


    2.Is the IF output phase correct ?
    

    ・IF１（20PIN）：0deg
    

    ・IF2（18PIN）：-90deg
    


    3.How to select the appropriate sideband ?
    

    Following is correct ?
    

    To select the lower sideband, connect the IF1 pin to the 90° port of the hybrid and the IF2 pin to the 0° port of the hybrid.
    

    To select the upper sideband, connect the IF1 pin to the 0° port of the hybrid and the IF2 pin to the 90° port of the hybrid.
    


    Best regards,
    

    sss

      Hi,
      

      1) There isn't a hybrid on the LO path so the phase on LO port of each mixer will be the same as the input phase on the LO pin of the HMC1113.
      

      2) We do not specify the I and Q ports here, instead we state the configuration to select the appropriate sideband (see 3).
      

      3) USB (Low Side LO): IF1 to 0 degree port of hybrid, IF2 to 90 degree port of hybrid.
           LSB (High Side LO): Reverse the connections from the USB.
           This is assuming that the sum port of the hybrid is used as the output.
      

      

      Thanks,
