  • Patent number: 7810057
    Abstract: The present invention provides a method and an apparatus for assessing a capability, for example, linearity of an amplifier, such as that of a power amplifier including a radio frequency amplifier. In one embodiment, the method comprises defining a first figure of merit for a power amplifier based on a loss of linearity relative to a predefined linearity requirement for the power amplifier and/or defining a second figure of merit based on the first figure of merit and dependent upon a minimum frequency within a predefined frequency band for the power amplifier, characterizing the linearity thereof. In this manner, using a test setup, for digital mobile communication networks deploying one or more higher order modulation schemes with complex wireless transmission that results in non-constant envelope signals, linearity of power amplifiers in transceivers, such as a mobile station or a base station, may be sufficiently described.

  • Patent number: 7587218
    Abstract: The present invention provides a method and an apparatus for using power of a pilot channel to control an output power from a transmitter, such as a base station transmitting spread spectrum signals. In one embodiment, a method for controlling an output power from a transmitter associated with a communication node (e.g., Node B) in a wireless network, such as a digital cellular network is provided. The method comprises extracting an indication of a pilot channel power from a portion of an output signal of the transmitter and controlling a control loop having one or more control devices in the transmitter based on the indication of a pilot channel power such that the pilot channel power stays substantially constant over a period of time. In this manner, using a closed power loop controller, a transmitter may overcome the problem of measuring the power of a non-constant spread spectrum signal and a traffic independent measure may control a cell size.

  • Patent number: 7433668
    Abstract: The present invention provides a method and an apparatus for controlling a Q-factor for a filter. The method comprises stabilizing an active feedback to provide a variable feedback in a filter, varying the active feedback based on an input signal to the filter, and producing a desired Q-factor for the filter at a first frequency band, in response to the variable feedback. The method further comprises reconfiguring a center frequency and a bandwidth of the filter based on a channel bandwidth of the input signal to the filter to adjust the Q-factor for the filter in response to a second frequency band different than the first frequency band. By reconfiguring a center frequency and a bandwidth of a filter, the Q-factor for the filter, such as a flexible or reconfigurable filter, may be controlled across a multiplicity of frequency band signals.

  • Patent number: 7155182
    Abstract: The invention proposes a device for high-frequency and/or radio-frequency tuning comprising within one IC-package a first variable capacitor (C1) and at least one second capacitor (C2), each of the at least one second capacitor (C2) being fixed or variable respectively, at least one signal path connected to the first variable capacitor (C1) and providing at least one input and one output port (rf-port1, rf-port2) and at least one controllable switching means (SC2) for individually connecting and disconnecting at least one of the at least one second capacitor (C2) into the signal path or from the signal path, in particular in parallel to the first variable capacitor (C1).

  • Publication number: 20030218514
    Abstract: A universal tuning and matching device for providing increased reconfiguration flexibility for high frequency or radio frequency signal transmission systems and/or applications by simultaneously reducing undesirable parasitic influences. The device for high frequency tuning and/or matching may be incorporated within one IC-package at least two capacitors (C1, C2, C3) and two inductors (L1, L2, L3), at least one signal path with at least one input and one output port (RF-port1, RF-port2, RF-prot3) and controllable switching means (1C1, 1C2, 1C3, 1L1, 1L2, 1L3) for individually connecting and disconnecting at least one of the capacitors (C1, C2, C3) and/or at least of the inductors (L1, L2, L3) into the signal path or from the signal path.
