INTRODUCTION

is possible with the EK54 evaluation kit. The EK54 includes

both the universal EVAL36 board and the EVAL46 substrate.

The use of EVAL36 and EVAL46 allows for a large area of

breadboarding space to work with while allowing a surface

mount substrate for the PA60DK. The PA60DK ampliﬁ er

may be surface mounted directly to the EVAL46, a thermally

conductive but electrically isolated substrate. The PA60DK

is soldered to a DUT foil footprint area the size of the

heatslug as shown in Figure 1. The metal substrate is cost

effective and can allow the PA60DK to dissipate power up

to the datasheet rating.

BEFORE YOU GET STARTED

• All Apex amplifiers should be handled using ESD

• Review the Apex product datasheet and operating

• Always provide the appropriate heat sinking. Power

• Always use adequate power supply bypass capacitors,

• Do not change connections while the circuit is powered

• In case -Vs is disconnected before +Vs, a diode between

• Initially set all power supplies to the minimum operating

• Check for oscillations up to and above the unity gain

ASSEMBLY

assembled to the EVAL46 substrate using surface mount

processes. Solder paste may be dispensed or screen-printed

on the DUT pads. The heat slug on the back of the PA60DK

provides maximum heat dissipation capabilities when soldered

to the foil footprint area. The PA60DK should be reﬂ owed to the

substrate using a solder reﬂ ow furnace. If this is not available,
