Abstract
Various embodiments of switched amplifiers are disclosed herein. In some embodiments, a switched amplifier may include a first amplifier; a second amplifier; an input matching network common to both the first and second amplifiers; and at least one switch to couple an input of the switched amplifier, via the input matching network, to one of the first amplifier or the second amplifier. In some embodiments, a switched amplifier may include a first amplifier; a second amplifier; an input matching network common to both the first and second amplifiers or an output matching network common to both the first and second amplifiers; and a bias generation circuit to selectively (1) provide a first bias current to the first amplifier or (2) provide a second bias current to the second amplifier, wherein the second bias current is less than the first bias current.
