Hi,
I am trying to design 2 stage class AB power amplifier in ADS. I want to get 30 dbm output power.
I started with loadpul simulation for second stage but I never get 30 dbm.
My VDD is 2.5 since I have max 2 breakdown voltage and I set V=3 for cascode bias. I am setting the gate bias to be 0.75
Pout =1/4 VDD.Imax assume 31 dB considering output matching loss => Imax = 2 A , IDC for class AB is IDC=Imax/3 -> IDC = 0.66
max gain and stability
