Abstract
The invention provides a method and apparatus for applying test signals to a multiport amplifier (MPA) and a method, apparatus and system for determining parameter adjustments for an MPA. Applying test signals to an MPA is performed so as to provide an output signal indicative of parameter adjustments for the MPA, the multiport amplifier arrangement comprising an input network, an amplifier unit and an output network, where the method includes providing a test signal directly to a point in the multiport amplifier arrangement between an output of the input network and an input of the amplifier unit. The method of determining parameter adjustments for a multiport amplifier arrangement includes receiving first and second output signals associated with an output of the multiport amplifier arrangement, the first output signal corresponding to a first signal path through the multiport amplifier arrangement and the second output signal corresponding to a second signal path through the multiport amplifier arrangement and determining parameter adjustments based on the first and second output signals.
