HMC951B NF low IF frequencies

Question

Good morning, 
 could you give me Noise Figure data of HMC951B @ low IF frequencies (at least with IF = 2MHz), please? 
 Thank you

Hi, 
 We haven't measured the NF at IF of 2MHz but we have measured the CG and image rejection till IF frequency of 1MHz and these two parameters don't change as IF frequency becomes smaller so the NF should be around 2dB as stated in the datasheet. 
 One thing to be careful when downconverting to such low IF frequencies is that the phase noise of the LO source might affect your noise floor- so you will need a very low phase noise LO source. 
 Thanks,)
