I'm beginning to think I'm an idiot. I just did a search through the 21st edition of the ARRL Antenna Handbook for "IP3", "OIP3" and "Third Order Intercept" and the results showed nothing.
I couldn't find the terms in an Amateur radio testing doing a Google search.
How can I start to learn this stuff, so that when @Ubbe adds a comment to this thread, I can get even the slightest inkling of what he is talking about?

Could someone please explain preamp specs in layman's terms?
There has been a decent amount of talk about preamps here lately, and I even use them myself. Figures such as gain and noise figure are fairly simple to understand, but other things such as directivity, IP3 etc., while I've read what these still don't make a lot of sense, at least to me. If...
Preamp IP3
On my SDS200, I am using a Mini Circuits LNA with admittedly too much gain (~27 dB but I have an attenuator on it) and the IP3 is about 30 dBm. I see MC also sells a 13 dB LNA with an IP3 of around 40 dBm. I have read posts by a few others here who seem quite knowledgeable on the subject, so I...

You probably need a background with a RF technology education to grasp everything. But that's what forums are for, to get advice about things that are too difficult to understand.
