a. The BCM4319 supports a functional operating range of –30° to +85° C. However, the optimal RF performance
specified in this datasheet is only guaranteed for temperatures from –10° to +55° C.
Absolute Maximum Ratings
These specifications indicate levels where permanent damage to the device can occur. Functional operation is
not guaranteed under these conditions. Operation at absolute maximum conditions for extended periods can
adversely affect long-term reliability of the device.
