EVALUATION KIT
EK61 is an easy to use engineering platform for prototype
evaluation. The PC board is a good starting point for an applica-
tion specic layout. The amplier is sold separately. Common
hardware such as screws, nuts and user's preference for I/O
connectors are not provided.

The EK61 includes both the universal EVAL36 board and the
EVAL61 substrate. The use of EVAL36 and EVAL61 allows for
a large area of breadboarding space to work with while allow-
ing a surface mount substrate for the PA79DK. The PA79DK
amplier may be surface mounted directly to the EVAL61, a
thermally conductive but electrically isolated substrate. The
PA79DK 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 PA79DK to dissipate power up to
the datasheet rating.
