Claim One:
1. An amplifier comprising: a device package configured to be connected to a printed circuit board (PCB), wherein the device package is distinct from the PCB, and the device package includes first, second, third, and fourth input leads, first, second, third, and fourth output leads, a first amplifier path connected between the first input lead and the first output lead, wherein the first amplifier path includes a first input matching network coupled to the first input lead, and a first amplifier stage coupled between the first input matching network, and the first output lead, and wherein the first amplifier stage forms a portion of a main amplifier path of a Doherty amplifier, a second amplifier path connected between the second input lead and the second output lead, wherein the second amplifier path includes a second input matching network coupled to the second input lead, and a second amplifier stage coupled between the second input matching network, and the second output lead, and wherein the second amplifier stage forms a portion of a first peaking amplifier path of the Doherty amplifier, a third amplifier path connected between the third input lead and the third output lead, wherein the third amplifier path includes a third input matching network coupled to the third input lead, and a third amplifier stage coupled between the third input matching network, and the third output lead, and wherein the third amplifier stage forms a portion of a second peaking amplifier path of the Doherty amplifier, and a fourth amplifier path connected between the fourth input lead and the fourth output lead, wherein the fourth amplifier path includes a fourth input matching network coupled to the fourth input lead, and a fourth amplifier stage coupled between the fourth input matching network, and the fourth output lead, and wherein the fourth amplifier stage forms a portion of a third peaking amplifier path of the Doherty amplifier.
