INTRODUCTION
This easy to use kit provides a platform with good circuit board layout and grounding to evaluate Power
Amplifiers PA07, PA08, PA09, PA85, PA88, and PA96. With additional prototype area, it is flexible enough to
analyze a multitude of standard or proprietary circuit configurations. All components are provided with the
kit. Similar circuitry is used for evaluation and the circuit for a particular package can be changed using jump‐
ers. External connections to the evaluation kit can be made through the connectors at the edges of the cir‐
cuit. The circuit provides an input line termination of 50 Ω.
The PA07 and PA09 are configured for a gain of 12. The PA08 and PA96 are configured for a gain of 21.
The PA85 and PA88 are configured for a gain of 53. This evaluation kit provides flexibility for modifying the
gain, in inverting or non‐inverting mode.
