INTRODUCTION
This easy-to-use kit provides a platform for the evaluation of linear power amplifiers circuits using the
PA91 pin-out. With ample breadboarding areas it is flexible enough to analyze a multitude of standard or pro-
prietary circuit configurations. Critical connections for power supply bypassing, compensation and current
limiting are pre-wired. Components not usually readily available in engineering labs are provided. External
connection to the evaluation kit can be made via the terminals at the edge of the circuit board. These termi-
nal pads are suitable for standard banana jacks or direct soldering of wires. The schematic is shown in Figure
2.
