2.1 Recommended Operating Conditions

Symbol
V_VSP Supply voltage of transmitter power stage
I_VSP Current consumption of transmitter power stage - refer to the
formula below
P_VSP Peak pulse power input to transmitter power stage (I_VSP *
V_VSP * Duty Cycle)
V_ANT Antenna resonance voltage
Antenna resonance voltage (Pulse width setting ≤ 25%)
V_ANT-25
V_ANT- Minimum antenna resonance voltage for correct operation of ATI

T_oper Operating free-air temperature range
T_store Storage temperature range
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%.
Table 9 shows the recommended operating conditions.

Parameter
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.
