Is it mandtory the difference between IIP3 and P1dB compression point must be 10 dBm
I am using pHEMT transistor for design of my LNA. I have got 46 dBm as the IIP3 and P1 dB as 12 dBm.
I have heard that difference between IIP3 and P1 dB must be 10 dBm. Is it mandatory difference between P1 dB and IIP3 must be 10 dB or even difference crosses more than 10 dB as we were getting 34 dBm difference, is it correct or any thing wrong in measuring. We have measured P1 dB compression point with respect to output power.
Difference between P1 dB and IIP3 must be closer to 10 dBm, is it O.K. or if difference cross more than or less than 10 dBm, as such more than 20 dBm, 30 dBm , 35 dBm or as such less than 5 dBm, 8 dBm , 2 dBm, is it wrong.
Can you clarify
