EK27U Rev I

Evaluation Kit

EK27

APPLICABLE PARTS (SOLD SEPARATELY)

• PA50

• PA52

INTRODUCTION

This easy to use kit provides a platform with good circuit board layout and grounding to evaluate linear

power amplifier circuits using the PA50 / PA52 pin out. 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. External connections to the evaluation kit can be made through the connectors at the edges of the circuit.

The circuit provides a line termination of 50 Ω.

The Power amplifiers are configured for a gain of 21. This evaluation kit provides flexibility for modifying

the gain, in inverting or non-inverting mode and for using a differential amplifier configuration.
