Hi,
Based on doherty power amplifier theory, the main (carrier) amplifier should be matched to 100 ohm at low input power levels and to 50 ohm at high power levels. Through performed load pull, I got two different impedances for low and high power matching.
1. Z= 14.322+j4.960 to be matched to 100 ohm at low power levels
2. Z= 7.311+j7.596 to be matched to 50 ohm at high power levels
My question is, How I can design one matching network that could satisfy the above two conditions? Please advice me with this issue. Thanks in advanced
