Matching Network Design for Power Amplifiers

The adequate modeling of matching networks is crucial for the success of power amplifier design. Due to a set of simulation tools included, WIPL-D Microwave provides a complete environment for accurate and efficient modeling and design of power amplifiers.

Example of a commercially available power transistor has been presented to explain the matching network topologies preferred for the power amplifier application and to demonstrate the outline of the complete design flow. The necessity to introduce electromagnetic analysis to accurately model typical power amplifier matching networks or otherwise face the significant inaccuracy due to the effects of coupled discontinuities has also been explained.

The design has been carried out for the microstrip substrate recommended by a manufacturer. If necessary, it can be easily adapted to any other substrate preferred providing that the substrate thickness conforms with the height of the transistor lead and the first transmission line element in the networks remains wider than the width of the transistor lead.
