APPARATUS FOR MATCHING IMPEDANCE IN RADIO FREQUENCY AMPLIFIER |
摘要 |
<p>An impedance matching network for a radio frequency (RF) amplifier includes multiple stages connected to each other in a first to last order. A first stage produces an RF output signal, and a last stage receives an RF input signal. Each stage includes a first inductor connected to produce an output signal, a second inductor connected to receive an input signal from a next stage, a capacitor connected between the first and second inductors and a ground. In addition, each stage other than the first stage further includes a first switch to by-pass the first and second inductors, a second switch connected between the first and second inductors and the ground, and a controller for controlling the first and second switches to select a particular power level of a set of power levels.</p> |
