INTRODUCTION
This easy-to-use kit provides a platform for the evaluation of linear power amplifiers circuits using the
PA90/PA91/PA92/PA93/PA98 pin-out. With ample breadboarding area it is flexible enough to analyze a mul
-
titude of standard or proprietary circuit configurations. Critical connections for power supply bypassing, com
-
pensation and current limiting are pre-wired. Components not usually readily available in engineering labs
are provided. External connections to the evaluation kit can be made via the terminals at the edge of the cir
-
cuit board. These terminal pads are suitable for standard banana jacks or direct soldering of wires. The sche
-
matic is shown in Figure 2.
