HEAT SINKING
The NuPower Xtender is offered as a stand-alone module, or as part of a kit, which also includes a fan-
cooled heat sink with an AC/DC adapter and an interface cable with banana jack plug terminations. The
fan-cooled heat sink provides sufficient cooling for operating the NuPower Xtender at room
temperature (25 °C), however higher ambient temperatures may require additional heat-sinking to
maintain a baseplate temperature below 60 °C at 100% transmit duty cycle.
Figure 3:
The NuPower PA Kit offers “out
-of-the-
box” operation for the user.
The fan-cooled heatsink
with an AC/DC adapter is shown with an example PA (NuPower Xtender not shown).
Caution: The use of external heat-sinking is required especially for those applications
requiring high duty cycle operation (e.g. continuous wave) or for extended on-time testing.
Operation without a proper heat sink under these conditions will cause permanent damage
to the product and will void the product warranty.
