Hi,  
My system configuration, input power level, after front-end gain and external step attenuation, is about -14 ~ -10 dBm@1GHz. If this kind of input power level is applied into LMS7002M RX input, what will be the IF output power level in terms of dBm?  
I need about RX total gain of 30dB corresponding NF ~3dB due to the total NF consideration. I do not want to saturate external ADC that I am considering to use which has about -4dBm FS. Can you advise input / output P1dB @ 1GHz of the analog receiver chain?

Thanks,
