    摘要: A power detection system implemented using a pair of directional couplers and a transmission line (or equivalent) disposed between the directional couplers, wherein the transmission line (or equivalent) provides a 90° phase shift between the directional couplers. Accurate power detection is provided by combining the powers detected at each of the directional couplers, whereby the combined power is independent of load phase. The total power in the forward case is given by Pc1=2*Pf*C, where Pf is the forward power and C is the coupling coefficient the directional couplers. The total power in the reflected case is given by Pc1=2*Pf*C*(ρ2+D2), where Pf is the forward power, C is the coupling coefficient of said directional couplers, ρ is the reflection coefficient, and D is the directivity of the directional couplers.

    摘要: A power sourcing equipment-powered device (PSE-PD) combination unit requests inline power from a connected PSE or other PSE-PD combination unit by having the PD portion of the PD-PSE combination unit adapt its electrical characteristics, if necessary, to obtain the maximum power available. The PD-PSE combination device keeps track of available power less power consumed locally with a summation unit. A PSE manager unit grants PD power requests from downstream devices based upon the available power left (e.g., original PSE power less losses less local consumption).

    摘要: A predistortion linear power amplifier and method employs parallel predistortion cancellation. In one embodiment the predistortion linear power amplifier (200) utilizes a signal splitter (202) to split an input carrier signal. A first amplifier, such as a main power amplifier (206) in a first path (214), receives the first split carrier signal (216). A signal predistortor (210) in a second path (218) is operatively coupled to receive a second split carrier signal (220) and to output a predistorted carrier signal (226). A second amplifier, such as a linear power amplifier (212) serially coupled with the signal predistortor (210) in the second path, amplifies the predistorted carrier signal (226). A signal combiner (208) operatively combines the output from the first amplifier and the output from the second amplifier to provide an amplified carrier output signal (230) from which nonlinear distortion has been substantially cancelled.
