OK, that makes sense. I was assuming you meant receiver IP3, but when
you labeled something as OIP3, it made me think you meant the TX.
Typically, for a device like an amplifier or mixer, the manufacturer
will quote it in either IIP3 or OIP3, depending on which sounds better
:) Amplifiers have gain so the OIP3 is a bigger number, so they quote
that. Passive mixers have loss, so the IIP3 is a bigger number, and
they quote that.
Typically, for a complete receiver system, IIP3 is the number quoted,
and for a complete transmitter OIP3 is quoted, since those are the
measuring points.
In any case, +10 dBm for the IIP3 of the receivers is about in line with
reality, and is a very good number (if I do say so myself :) for a
system like this. This will of course change with gain settings, in any
case.

The IP3 of the receiver. Sorry, I should have mentioned earlier.

It is not clear to me whether you are talking about IP3 of the
transmitter or IP3 of the receiver.

Hi Everyone:
Is there any information on the IP3 of Flex 900 boards. I was not
lucky to
find any specification documents on the boards.
I tried doing some experiments to find out the IP3 and my
results show
37.5dBm, that is a good figure. I am not too sure whether it
really
is so
high.
If anyone could please help me with any information that you
may have
regarding the IP3 of Flex 900 boards, to that matter any
other board
will
also give me a decent idea about these boards.
Thanks loads in advance.
Kind regards,
Shabbir
