INTRODUCTION

of linear power amplifiers circuits using the PA97 pin-out. With

ample breadboarding areas it is flexible enough to analyze

a multitude of standard or proprietary circuit configurations.

Critical connections for power supply bypassing 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

terminal pads are suitable for standard banana jacks or direct

soldering of wires. The schematic is shown in Figure 1.
