Abstract:
1. An RF driver circuit comprising: a first RF driver stage having a first signal input configured to receive a first signal, a first supply input configured to receive a second signal, and a first output, said first RF driver stage including a switch assembly and a resistive assembly associated therewith; a second RF driver stage coupled in series with said first RF driver stage, said second RF driver stage having a second signal input coupled to said first output, a second supply input configured to receive said second signal, and a second output; and an AM modulator coupled to said first and second supply inputs and configured to receive an input signal and to provide said second signal, said first RF driver stage, said second RF driver stage, and said AM modulator implemented to combine and amplify said first signal and said second signal and to provide at said second output an amplified output signal based thereon.
