ABSTRACT: Load Pull is an invaluable tool for the mobile phone community, helping to design more robust and efficient products and guarantee their successful functionality in real-world environments. Mobile phones and their subcomponents can be tested in various stages: the internal power amplifier (PA), the front-end module (FEM), or the phone in its entirety. Maury MT993 ATS software is used to test PAs and FEMs for dozens of parameters including Power, Gain, Efficiency, Harmonic Power, Intermodulation Distortion (IMD), Error-Vector Magnitude (EVM), Adjacent Channel Power Ratio (ACPR), etc. Maury MT910 series software is a standalone application designed specifically for the testing of mobile phones in transmit and receive modes, for output power and sensitivity respectively, as a function of VSWR magnitude and phase.
