Emulation of array coupling influence on RF power amplifiers in a measurement setup
Paper i proceeding, 2016
A new method for emulating array coupling influence on RF power amplifiers in a measurements setup is presented. This method is based on an iterative procedure, where a signal is injected towards the output of the power amplifier, based on the output signal of the power amplifier measured in the previous iteration. Thus any coupling can be emulated by injecting an appropriately scaled signal. Emulation results are presented for a 6 W GaN amplifier. The results are verified using two identical amplifiers connected by a fixed attenuator.
