1. A combiner for connection to the output terminals of a Doherty amplifier having a main amplifier and one or more peaking amplifiers, the combiner comprising:
an inverter circuit comprising at least a first network and a second network, wherein each of the first network and the second network includes lumped elements, and a transformer circuit comprising at least a third network and a fourth network, wherein each of the third network and the fourth network includes the lumped elements, wherein the lumped elements are selected from a group of capacitors and inductors, wherein the first network includes:
a first capacitor coupled in shunt between an output terminal of the main amplifier and a ground terminal;a second capacitor coupled in shunt between a first inductor and the ground terminal; andthe first inductor connected to the first capacitor and the second capacitor; and wherein the second network includes:
a third capacitor coupled in shunt between output terminals of the one or more peaking amplifiers and the ground terminal;the second capacitor coupled in shunt between a second inductor and the ground terminal; andthe second inductor connected to the second capacitor and the third capacitor. |
