MULTIMODE RF AMPLIFIER SYSTEM

摘要

Multimode radio frequency (RF) amplifier systems and techniques are disclosed. In one embodiment, a multimode radio frequency (RF) amplifier system has a first RF amplifier and a second RF amplifier. The first RF amplifier may support a first RF communication standard. The second RF amplifier may support a second RF communication standard. The first RF amplifier includes an auxiliary circuit. The auxiliary circuit may provide a service or a utility to a second RF amplifier. For example, the auxiliary circuit may generate a supply voltage to power the second RF amplifier.
