  • Reconfigurable power amplifier and use of such amplifier for making a multi-standard amplification stage for mobile phone communications
    Patent number: 8115547
    Abstract: A reconfigurable power amplifier includes at least one amplification circuit (E1, E2), and a circuit (6) for controlling the amplification circuit so as to adapt its operation according to an applied input signal (RFin). The circuit for controlling includes a circuit (4, 5) for modifying the compression point of the amplification circuit and for adapting the gain of the amplification circuit in such a manner as to increase the power added efficiency of the circuit for the modified compression point.

  • Waveguide quardruple mode microwave filter having zero transmission
    Patent number: 6879226
    Abstract: The invention relates to a quadruple mode microwave filter having coupled cavities with a plurality of transmission zeros, said filter comprising at least one rectangular parallelepiped-shaped quadruple mode cavity, at least two rectangular irises, and two input/output waveguides. Tuning and coupling of the filter are obtained exclusively by the dimensions and mutual disposition of the at least one resonant cavity and the irises, without any screw or other tuning mechanism. All the faces of the cavities and the irises are either parallel or perpendicular to each other. In a preferred embodiment the irises are offcentered along the two transverse axes. According to one advantageous feature, the input mode and the output mode are the same, preferably the TE 10 fundamental mode.

  • Dual-mode microwave filter
    Patent number: 6538535
    Abstract: The invention provides a dual-mode microwave filter, comprising a rectangular resonator of length l, height b, and width a operating in two distinct modes (m, 0, n) and (p, 0, q) from a single family of modes and presenting the same direction as the E field, and wherein coupling and mode excitation discontinuities are inductive and in the same direction.
