INTRODUCTION

linear power amplifiers circuits using the MP108FD & MP111FD

pin out. With ample bread boarding areas it is flexible enough

to analyze a multitude of standard or proprietary circuit con-

figurations. 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 terminal block and terminal

pads at the edges of the circuit board. The terminal pads are

suitable for soldering standard banana jacks or direct wiring

of wires. Additionally, banana jacks and a BNC connector can

be inserted into the holes at the edge of the board and wired

to the numbered terminal pads.

BEFORE YOU GET STARTED

• All A pex Precision Power amplifiers should be handled using

• Do not change connections while the circuit is powered.

• Initially set all power supplies to the minimum operating

from the "DUT side" of the board. On the "component side"

of the board, solder all cage jacks having solder pads (7, 9,

10, 23, 24, 26, 29, and 31 have no solder pads). Make sure

the cage jacks are fully seated before soldering. Be careful

that solder does not flow into the cage jacks. Remove the

unsoldered cage jacks with the carrier strip segments.

engage the cage jacks. Alternately, sight through the align-

used to mount the amplifier. In either case be sure the pins

of the amplifier are engaged with the cage jacks and then

continue pushing the PCB assembly in the area between
