AD9371 Noise Figure and IIP3 specification

Hi,

We have purchased the evaluation platform for AD9361 and I've evaluated the same.

The NF and IIP3 of AD9361 are 2dB and -18dBm respectively.

Recently when I glanced through the datasheet of AD9371. I found the specifications to be on the higher side.

The NF and IIP3 are 12dB and 22dBm respectively. 

Is it the application which demands such a deviation in the specification? Is it targeted for specific application which requires a degraded NF specification but a high IIP3 front-end?

Or does it mean that we need to use an LNA with the AD9371?

Regards,
