ABSTRACT:
The invention addresses the problem of obtaining ways and means for providing a compensational gain, which can be used for gain compensation in connection with power amplifiers and other devices. According to the invention a power splitter splits a signal into two components. A phase shifter introduces a frequency dependent phase shift in one the components. A change of amplitude is introduced in one of the components. A combiner combines the components. By selecting appropriately the frequency dependent phase and the change of amplitude, a desired gain compensation characteristic is achieved.
