Automatic Load-Pull Tuner

This student team worked to build an automated load-pull tuner, a tool used for the RF engineers to characterize new transistors and test the performance of newly designed radio frequency (RF) Power-Amplifiers. The team designed a circuit (delivering the PCBA) with a control firmware and a graphical user interface (GUI) to acquire the required data and save them in the computer. The combination of PCBA, firmware, and GUI enables RF Engineers to deliver pulses, change the load to the amplifier, and acquire test data from an oscilloscope for their design analysis.
