4 Thermal Considerations

The radio dissipates a maximum of 7.6watts. Consideration must be given to thermal management such
that sensitive components on the card do not exceed their maximum operation temperature. It is
recommended that the integrator use an aluminum heat sink adjacent to the RF shield.
The following table provides thermal info and constraints that the integrator must consider in designing
the thermal management scheme.
