Abstract
A power amplifier system is disclosed having an N number of transistors coupled together drain-to-source between a supply node and a fixed voltage node, wherein a first one of the N number of transistors coupled nearest to the fixed voltage node is configured to operate as an amplifying device in an ON-mode, and remaining ones of the N number of transistors are configured to operate as cascode devices in the ON-mode and to operate as turned-off switches in an OFF-mode. A controller is configured to place the N number of transistors in the first mode when a radio frequency (RF) signal is to be amplified by the first one of the N number of transistors and to place the N number of transistors in the second mode when the RF signal is not to be amplified by the first one of the N number of transistors.
