HMC1065LP4E : NF@IF

Question

Hi All. 
 I have a question about HMC1065. 
 Our customer evaluated this device for Ka band FMCW radar. 
 At the lower IF frequency, NF has decreased by 6dB/decade. 
 Does ADI has detailed data? 
 Can this device be used under these conditions? 
 
 *Mesurement conditions, 
 Lo in=2dBm, fLo=16.25~16.75GHz 
 IF out =DC~

for X-band, HMC905 is no problem. 
 
 Best regards, 
 Hiroshi.

Hi, 
 The noise figure degradation close to DC is due to the flicker noise effect. This is standard for any mixer. The amount of degradation will change between different processes but it will still be there. The HMC524A is still not released and going through early evaluation so we cannot provide that measurement yet. HMC524A is scheduled for release in Q3 of ADI's fiscal year. 
 Thanks,)
