Hello,
I am using ADS to design a symmetrical Doherty amplifier. I am using Quorvo's (Triquint) device: T1G6001528-Q3. I know how to bias the transistor for class AB and class C operation so that I have a Carrier amplifier and Peaking amplifier. The next step is to find my optimum load impedance for both transistors using loadpull analysis.
My question is what input power level should I drive each amplifier to conduct loadpull analysis to find each optimum load impedance? I have read a variety of literature and have not found a straight forward answer. Any help is appreciated.
