Optimization of Power Added Efficiency and Third Order Intermodulation in Solid State Power Amplifiers, using Data Processing Software Coupled to Single Tone Active Source and Load-Pull System. Extension to Class F Operation

A fully calibrated and automatized single-tone test set-up, using both active source and load-pull techniques allows to built an accurate data-file, characterizing any non-linear two-port device. Appropriate data processing routines provide optimized operating conditions of the device under test in terms of added power, efficiency and third order intermodulation. Therefore such a measurement system reveals to be a precious laboratory tool to aid optimized power-circuit design.
