Latest Patents
Risto Väisänen's latest patents include a method and circuit arrangement for processing a received signal. This invention involves separating a direct voltage component of a signal that has been received and converted to a baseband. The first separator in the signal line controls the direct voltage components of both the signal preceding and following it through control signals. This allows for a baseband signal line preceding the first separator to be direct current coupled.
Another significant patent is a linear power amplifier arrangement and method for its operation. This arrangement provides a selectable amount of amplification to a radio frequency signal. It comprises a first parallel amplifier branch and a second parallel amplifier branch, with means for conducting the radio frequency signal to be amplified selectably to one of the branches. The first parallel amplifier branch includes a series connection of a predistorter and a nonlinear amplifier, where the predistorter compensates for the nonlinearity of the nonlinear amplifier.
