2.2 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.
