    Abstract: Embodiments are described for modules, multi-stage systems, and related methods for radio frequency (RF) power amplifiers with reduced size and weight requirements. Fluid cooling is incorporated directly into the power amplifier (PA) module design rather than requiring PA modules to be mounted on separate cooling devices. For one embodiment, a PA module includes a circuit board, RF circuit components, a ground plane, and a cooling plate having one or more cooling channels to receive a cooling fluid. The cooling channels are positioned to dissipate heat from the RF circuit components through the ground plane. For a further embodiment, the PA module also includes RF bias and power electronics within a housing for the PA module without requiring an external control board or power conversion electronics. Also disclosed are multi-stage PA systems having a plurality of PA modules that are similarly cooled using cooling channels.

A current path on the primary side is provided for flow of a current that is induced on at least one primary winding when a power amplifier coupled to that primary winding is in “off” state. As a result, the induced current is prevented from flowing in to the power amplifier that are in “on” state. Further, the current path isolates the power amplifiers from each other thereby enabling the power amplifiers to operate at the rated efficiency. In one embodiment, the current path is provided using a resistor network.

  • Patent number: 8130057
    Abstract: The present invention relates to a lumped cross-coupled Wilkinson circuit having a pair of magnetically cross-coupled inductive elements coupled to an isolation network. By magnetically cross-coupling the inductive elements, which have a mutual inductance, the inductance of each inductive element will be significantly less than the inductance of each inductive element in an equivalent lumped traditional Wilkinson combiner. Since the inductance of each inductive element is less, the size of each inductive element may be significantly smaller and the resistive loss of the each inductive element may be significantly smaller. In one embodiment of the present invention, the lumped cross-coupled Wilkinson circuit operates as a lumped cross-coupled Wilkinson combiner. In an alternate embodiment of the present invention, the lumped cross-coupled Wilkinson circuit operates as a lumped cross-coupled Wilkinson splitter.

  • Patent number: 7675386
    Abstract: The various designs of capacitive or inductive coupling/decoupling fitted on cables in a medium voltage network are known, the inductive coupling circuits constantly inducing current in the sheath of the electric cable. The invention aims at obtaining ranges of capacitive coupling/decoupling for an inductive coupling circuit. Therefore, an inductive coupling unit comprising a ring enclosing the sheathed electric cable and a coil, coupled to said ring by induction and connected to a transmission and reception device, is designed such that, upon transmission the current of the message signal is directly induced in the conductor and, upon receptions only the conductor current is evaluated. In a first embodiment, a by-pass, located downstream of the inductive coupling unit and upstream of the defined surface, is connected to the sheath and to ground or to the compensation potential.
