Title: Arbitrary waveform predistortion table generation
Inventor: BRANDT PER OLOF
IPC: H03F1/32
Filed: 2005-09-26
Abstract: Predistortion that will compensate for distortion introduced by a power amplifier circuit (101) is determined by applying a time-varying reference signal (AMref, PMref) to the power amplifier circuit (101), wherein at each moment the time-varying reference signal has a reference amplitude (AMref) and a reference phase (PMref). A corresponding output signal (Ammea, Pmmeas) supplied by the power amplifier circuit (101) is measured, wherein at each moment the output signal has a measured amplitude (AMmeas) and a measured phase (PMmeas). Amplitude predistortion (AMpre) is determined by comparing the reference amplitude with (AMref) the measured amplitude (AMmeas), and phase predistortion (PMpre) is determined by comparing the reference phase (PMref) with the measured phase (PMeas). A relationship between the phase predistortion and the reference amplitude is determined such that, for any value of the reference amplitude (AMref), a corresponding value of the phase predistortion (PMpre) is identified.

Title: Transformer core comprising magnetic shielding
Inventor: PLOETNER CHRISTOPH
IPC: H01F27/24
Filed: 2006-02-10
Abstract: The invention relates to a transformer core comprising a core interior consisting of a magnetisable material. Magnetic leakage fluxes create eddy currents in the outer core regions, which lead to power losses and local overheating. Said leakage fluxes are channelled and conducted away from the outer region of the core interior by shielding, which partially encompasses the core interior and consists of at least one layered magnetisable material. This permits the formation of eddy currents in the core interior to be significantly reduced and thus prevents local overheating of the transformer core and power losses.
