INTRODUCTION
This easy-to-use kit provides a platform for the evaluation of
linear power amplifiers circuits using the PA50/PA52 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 terminal block and terminal pads at the edges of
the circuit board. The terminal pads are suitable for soldering
standard banana jacks or direct soldering of wires. The sche-
matic is shown in Figure 2.
BEFORE YOU GET STARTED
* All Apex amplifiers should be handled using proper ESD
precautions.
* Do not change connections while the circuit is powered.
* Initially set all power supplies to the minimum operating volt-
age allowed in the device data sheet.

ASSEMBLY
During assembly refer to Figure 1
1. Note that each circuit board side is identified. From the
circuit side of the circuit board (not the component side)
insert and solder cage jack MS04 at pins 1-12. Be sure
that the cage jack sits flush with the surface of the circuit
board.
2. Solder the surface mount ceramic capacitors to the com-
ponent of the circuit board at C3-C7.
3. Mount the electrolytic capacitors at C1 and C2 from the
component side of the circuit board and solder from the
circuit side of the circuit board. Note polarity and be sure
to fill the holes with solder. Use correct voltage capacitor
for your application.
4. Mount the terminal strip TS02 to the component side of the
circuit board. Make sure the terminal strip sits flat against
the circuit board and be sure to fill the holes with solder.
5. Use #14 sleeving to insulate and align at least 2 opposite
pins of the amplifier.
6. Add other components to complete your circuit design. Note
that the solder terminals labeled 2 and 3 are left for you to
connect to the amplifier via the components that you will
add for your particular design.
7. Push the four nylon spacers into the circuit board from
the circuit side of the circuit board at the four corner loca-
tions.
8. Apply TW05 thermal washer to the bottom of the PA50.
Mount the amplifier to the HS18 heat sink provided and
loosely attach with #6 screw and nut.
9. Place the assembled circuit board over the pins of the
amplifier making sure that the pin 1 location on the circuit
board matches up with pin 1 of the amplifier. Insert the pins
of the amplifier into the circuit board mating cage jacks.
10. Mount the circuit board assembly to the heat sink with #6
self tapping or sheet metal screws at the four corners of
the heat sink.
11. Tighten the screws that mount the amplifier to the heat sink
via the access holes in the circuit board.
