I'm trying to get a ballpark idea of how modulation and multitone signals will affect necessary power.

Say I have an OFDM signal that has a PAPR/crest factor of 10-14 dB. If I have an amp with a P1dB of 30 dBm does that mean I need to make sure the CW output is max 16 dBm so I'm not over driving the amp and getting distortion?

Basically, if I have a sig gen into an amp do I need to back off the output by the PAPR to prevent distortion? With two OFDM signals would it be by the sum of the PAPRs?

I'm looking at replacing my Samsung A71. I have 128GB storage plus a nearly full 256 GB SD card in it, so looking for something that will allow at least that much storage.

I do not want any phone from China.

From what I can find it looks like the A35 is the last Samsung with an SD card slot, but they're 3+ years old already. Everything else with 512+ GB seems to be $1000+ phones which is out of my price range.

I tend to keep my phones long term until they break, so want something for 5+ years if possible. WPT would be nice, since it seems like the charging port is the weak point for some phones. I don't play games or do that much, so doesn't need to be top of the line. I do take a lot of pictures though.
