High Performance RA-RFM RI-RFM-008B
February 2002
20
CAUTION:
Exceeding recommended maximum ratings may lead to
permanent damage of the RA-RFM.
The RA-RFM must not be operated in continuous transmit
mode when operated at full power output.
Install suitable heatsinks when operating the RA-RFM at
pulse widths smaller than 50%.

Note:
Free-air temperature is the air temperature immediately surrounding
the RA-RFM module. If the module is incorporated into a housing, it
must be guaranteed by proper design or cooling that the internal
temperature does not exceed the recommended operating conditions.
