Abstract

This paper deals with the evaluation of the traditional Travelling Wave Tube Amplifier (TWTA) output power model completed with an associated power efficiency estimation with multi carrier signal. A 120 W Ka Band linearised TWTA is used to propose a full comparison between simulated and measured results concerning up to four modulated carriers as an input signal. Three different regions of output operating point are proposed, each correlated to a growing complexity needed in signal simulation from CW to all multiplex composed by modulated carriers.
