摘要： A power amplifier includes a carrier amplifier path and a peaking amplifier path. The carrier amplifier path includes a carrier amplifier (208), and an impedance transforming network (214). The peaking amplifier path includes a peaking amplifier (210), an impedance transforming network (216), and a phase delay quarter wave element (226). The arrangement forms an inverted Doherty combiner where as the nominal impedance at a summing node (230) increases with increased conduction from the peaking amplifier, the load impedance at the output of the carrier amplifier decreases so as to maintain the carrier amplifier at a saturation point as the input signal (232) increases, and results in a reduction of the number of phase delay elements needed over a conventional Doherty approach. In a preferred embodiment the carrier and peaking amplifiers consist of cascaded stages, and are disposed on a common integrated circuit die (304). The impedance transforming networks and phase delay element are disposed on a common substrate (306), as is an input splitter network (308).

摘要： An integrated filter circuit and a method of fabrication are disclosed, wherein the integrated filter has an input and an output parasitic shunt impedance. Input and output electrical components are coupled to the input and output terminals, respectively, to reduce the input and output parasitic shunt impedances. The input and output electrical components each include one of a coil, a section of transmission line, a coil and tuneable capacitance connected in a series tuned circuit, or a coil and tuneable capacitance connected in a parallel tuned circuit. The integrated filter includes input and output multilayer ceramic integrated coils which may be positioned so that capacitive coupling between the coils substantially cancels inductive coupling therebetween, and/or an interlayer gridded ground wall is positioned between the input and output coils

摘要： A high Q multi-layer ceramic transmission line resonator (100) used for RF applications. The resonator (100) includes a plurality of strips (102) which are separated by a ceramic substrate (104). Each of the strips are interconnected using vias (110) passing through the ceramic substrate (104). The invention utilizes current manufacturing processes to fabricate an equivalent thick center conductor to effectively increase the Q factor. This allows for the resonator to be used in miniature RF communication devices utilized in high tier devices such as voltage controlled oscillators (VCOs) or integrated filter circuits.
