Transmitter Duty Cycle:

With supply below 13.5 volts:

8 W board only model - 100 % with added heat sink** maintained at 25

° C

8 W encased model - 33 % with case end cap*** maintained at 25

° C

5 W encased model - 50 % with case end cap*** maintained at 25

° C

(with heat sink or case end cap above 25

° C, degrades linearly to 0% at 60° C)

* pending model
** a heatsink can be added to the board only versions using the two holes next to the RF PA shield.
*** case end cap refers to aluminum extrusion end cap on opposite side from connectors.
