Abstract
A Doherty amplifier has at least one peaking amplifier which has first and second drain connections, wherein the first drain connection is connected to the output network, and the other second drain connection is connection to the load. By providing two drain connections, separate package leads to the peaking amplifier can be taken into account when designing the impedance inverter and an output impedance. In this way, the circuit operation can be optimized both for the impedance inversion function and for driving the output load.
