摘要： Apparatus, systems, and fabrication methods are provided for biasing amplifier arrangements inside device packages to a target quiescent current. In one embodiment, an amplifier device (102) has an output interface (109) and includes an amplifier arrangement (104) having an amplifier output (107) and impedance matching circuitry (108) coupled between the amplifier output (107) and the output interface (109). A method for biasing the amplifier arrangement (104) involves measuring or otherwise obtaining a voltage between the amplifier output (107) and the output interface (109), determining an estimated quiescent current through the amplifier arrangement (104) based on that voltage, and adjusting a bias voltage provided to the input (105) of the amplifier arrangement (104) based on a difference between the estimated quiescent current. In exemplary embodiments, the bias voltage is adjusted until the estimated quiescent current is substantially equal to a target quiescent current.

摘要： An embodiment of a plasma ignition system for an internal combustion engine having up to N cylinders includes a power splitter, N phase shifters, N amplifiers, a power combiner network, and up to N radiation devices. The power splitter divides an input RF signal into N divided RF signals. Each phase shifter applies one of multiple pre-determined phase shifts to one of the N divided RF signals to produce N phase shifted RF signals. The N amplifiers amplify the N phase shifted RF signals to produce N amplified, phase shifted RF signals. The power combiner network combines the N amplified, phase shifted RF signals to produce N output RF signals. Each of the radiation devices receives one of the N output RF signals, and produces a plasma discharge when a power level of the output RF signal is sufficiently high.
