1. A mobile device comprising:
a transceiver configured to generate a first radio frequency signal of a first fundamental frequency and a second radio frequency signal of a second fundamental frequency; and
a front-end system including a first power amplifier configured to amplify the first radio frequency signal and a second power amplifier configured to amplify the second radio frequency signal, and a power amplifier supply network configured to receive a power amplifier supply voltage at an input node, and to provide the 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 including a first harmonic termination circuit connected to the first distribution node and configured to provide an open circuit at about twice the first fundamental frequency, and a second harmonic termination circuit connected to the second distribution node and configured to provide an open circuit at about twice the second fundamental frequency.
