    Hi All,
    
 
    I have some questions about our circuit design (HMC659+HMC914).
    
 
    Please help take a look at the attachment and give me some advice. Thank you.
    
 
    Regards,

      Hi Kazumusa,
      
 
      Your proposed circuit might be ok only at very low frequency operation. At higher frequencies, there is likely issues with the proposed circuit. We do recommend that you attenuate the RF signal to less then 0.8Vpp. This is a more robust solution and would not impact the performance at any frequency.
      
 
      Thanks
