I found the same poor specs on LTC chips.

I've been looking for some IC chips that can be used for SDR. I've located
one. Its the RS2713 by RF Micro-Devices. I have requested a few samples from
them . I hope to have them by next week. I'll try the receiver first. This
chip takes the LO directly into it. The 90 Deg phase is built into the chip.
The operating freq. is half the LO freq. I'll update this post after I test
the chips. 73's WB8LGA
I have given a look at the specs of that chip. Unless something is escaping me,
they
do not seem particularly impressive... especially the input IP3 numbers...
Consider that QSDs with an input IP3 of more than +40 dBm have been built and
tested...
