Abstract:
1. A system for testing a communications device comprising: a portable wireless communications device comprising a transmitter transmits an RF signal and comprising a power amplifier and power amplifier matching network connected thereto; a monitoring device receives RF signals from the portable wireless communications device and analyzing the RF signals to determine total radiated power emitted from the transmitter; and an adaptive antenna equivalent circuit coupled to the power amplifier matching network, and a connection line extending between the adaptive antenna equivalent circuit and the monitoring device, and further comprising a controller operatively connected to said adaptive antenna equivalent circuit and configured to vary the impedance and adapt to impedance changes resulting from a change in frequency of the transmitter and adapt to different frequencies for testing, wherein said adaptive antenna equivalent circuit has an equivalent antenna impedance matched to the portable wireless communications device and the connection line and monitoring device based on transmit frequency to ensure that total radiated power of the RF signals is transmitted from the transmitter to the monitoring device.
