Abstract
A design method for designing a multi-path amplifier involves connecting an amplifier stage having at least two amplifier branches to a combiner stage; feeding a plurality of testing signals with one or more of a plurality of sweeping variables to the amplifier stage; measuring output signals at the output of the combiner stage depending on the plurality of testing signals; designing a structure of an input network stage for the amplifier stage on the basis of the measured output signals; and combining the designed input network stage with the amplifier stage to create an efficiency-optimized multi-path amplifier.

A method for designing a multi-path amplifier, the method comprising:
- connecting an amplifier stage having at least two amplifier branches to a combiner stage;
- feeding a plurality of testing signals with one or more of a plurality of sweeping variables to the amplifier stage;
- measuring output signals at the output of the combiner stage depending on the plurality of testing signals;
- designing a structure of an input network stage for the amplifier stage on the basis of the measured output signals, wherein the input network stage is not controllable or adjustable by a user input and is not controllable or adjustable by an adjusting unit;
- and
- combining the designed input network stage with the amplifier stage to create an efficiency-optimised multi-path amplifier.
A multi-path amplifier, comprising:
- a combiner stage;
- an amplifier stage having at least two amplifier branches connected to the combiner stage;
- an input network stage having at least one input terminal and at least two output terminals, the at least two output terminals being connected to respective amplifier branches of the amplifier stage, wherein the input network stage having been designed based on measured output signals at an output of the combiner stage, wherein the measured output signals are based on a plurality of testing signal fed within one or more of a plurality of sweeping variables to the amplifier stage, wherein the designed input network stage is combined with the amplifier stage to create the multi-path amplifier, and wherein the input network stage is not controllable or adjustable by a user input and is not controllable or adjustable by an adjusting unit.
