Abstract
Power amplifier supply networks with harmonic terminations are disclosed. In certain embodiments, a power amplifier system includes a first power amplifier that amplifies a first radio frequency (RF) signal of a first fundamental frequency, a second power amplifier that amplifies a second RF signal of a second fundamental frequency, and a power amplifier supply network that distributes a power amplifier supply voltage to the first power amplifier at a first distribution node and to the second power amplifier at a second distribution node. The power amplifier supply network includes a first harmonic termination circuit connected to the first distribution node that provide an open circuit at about twice the first fundamental frequency, and a second harmonic termination circuit connected to the second distribution node and that provides an open circuit at about twice the fundamental frequency.
