Abstract
A multiple power mode amplifier provides a low and a high power mode without using switches. This amplifier may be used in RF applications such as mobile telephones. In the low power mode, the power consumption of the amplifier is reduced, which will increase operation time, especially important for battery-operated devices. In one implementation, the amplifier includes a number of impedance matching network units (130, 140, 150, and 160), impedance transformer (170), and a power stage (120).
