Abstract: A circuit includes a first power transistor stage internally configured to function as a voltage-controlled current source, a second power transistor stage having an input impedance which varies as a function of input power and an interstage matching network coupling an output of the first power transistor stage to an input of the second power transistor stage. The interstage matching network is configured to provide impedance inversion between the input of the second power transistor stage and the output of the first power transistor stage. The impedance inversion provided by the interstage matching network transforms the first power transistor stage from functioning as a voltage-controlled current source to functioning as a voltage-controlled voltage source at the input of the second power transistor stage.

Abstract: An amplifier circuit includes an RF input port, an RF output port, a reference potential port, and an RF amplifier having an input terminal and a first output terminal. An output impedance matching network electrically couples the first output terminal to the RF output port. A first inductor is electrically connected in series between the first output terminal and the RF output port, a first LC resonator is directly electrically connected between the first output terminal and the reference potential port, and a second LC resonator is directly electrically connected between the first output terminal and the reference potential port. The first LC resonator is configured to compensate for an output capacitance of the RF amplifier at a center frequency of the RF signal. The second LC resonator is configured to compensate for a second order harmonic of the RF signal.

Abstract: A peaking amplifier is disclosed. The peaking amplifier includes a driver stage, a final stage, and an interstage matching network. The driver stage has a load impedance and is configured to generate a driver output based on an input signal. The final stage has a final stage input impedance and is configured to generate a peaking output based on the driver output. The interstage matching network is coupled to the driver stage and the final stage. The interstage matching network is configured to transform the final stage input impedance to the load impedance for the driver stage when the peaking amplifier is ON and to provide a short to an input of the final stage when the peaking amplifier is in an OFF state.

Abstract: A passive electrical component includes a substrate. A first metallization layer is formed on the substrate. A first dielectric layer is formed on the first metallization layer The first dielectric layer has a lower thermal conductivity than the substrate. A second metallization layer is formed on the first dielectric layer. An electrically conductive via provides an electrical connection between a first section of the first metallization layer and a second section of the second metallization layer. A thermally conductive via provides a thermally conductive path between the second section and the substrate. The thermally conductive via provides an open circuit termination to the second section of the second metallization layer.
