This paper describes a method for the detection of instabilities and their stabilisation under large-signal regime in multi-device paralleled power amplifiers. The symmetry of the amplifier is exploited for a simple and effective characterisation of odd- and even-order modes, and their reduction to equivalent single-transistor amplifiers. The nonlinear stability is then assessed by use of the conversion matrix. Examples of application are also given.

Abstract

This paper describes a method for the detection of instabilities and their stabilisation under large-signal regime in multi-device paralleled power amplifiers. The symmetry of the amplifier is exploited for a simple and effective characterisation of odd- and even-order modes, and their reduction to equivalent single-transistor amplifiers. The nonlinear stability is then assessed by use of the conversion matrix. Examples of application are also given.
