Hi,
I used to work with GaAs circuit (pHemt) and I use the "rule" that IP3 is 8 to 12 dB higher than 1 dB compression point.
I am not expert with non linearity effect so I have many question :
1) This "~10 dB" rule is valid for all GaAs circuit ? Amplifier but also Mixer, Phase shifter, switchs ?
Is cold pHemt are used this rule still good ?
2) And for other process : SiGe , GaN, SOI,... ?
What are the relationship ?
Thank you
