WebPAE of the Class J 45W GaN output amplifier stage. This - design achieved 45 to 59W saturated - output power, near constant 10-dB large-signal gain, and 45 to 62% PAE from 1.1 to 2.45 GHz. For a 45-W transistor, this reveals a Class J amplifier load that is at or near the optimal power and efficiency load targets over a 2.2:1 bandwidth.or 76% Web\$\begingroup\$ "Therefore Re must always be smaller than RL for small signals and <= 1/2 RL for full negative swing when AC coupled". Surely that's not necessary. Even if RL is very low it will be linear for a small enough input swing. For large signals there is no fixed requirement for the ratio of Re to RL - you can never get full negative swing no matter …
