摘要: Described embodiments provide a radio frequency (RF) amplifier system having at least one amplifier. The includes an RF input port, output port and drain bias port. At voltage modulator is coupled to the of voltage. selected by switching among plurality discrete voltages. filter circuit between controls spectral components resultant from transitions in when A controller dynamically adapts setting using multi-pulse voltages for first operating condition
