Abstract
A load pull system that has CDMA and GSM stimulus and response capability is presented. This novel system performs fundamental and harmonic tuning using a single, solid-state, impedance tuner without a multi-plexer or harmonic loops. Measurements of power, efficiency and spectral re-growth are obtained. Special consideration is made for the burst requirements of GSM. This paper presents the measurement system, harmonic tuning, CDMA and GSM examples.
