RF output Power can be reduced by the protection system depends on the case temperature
**
the rated output power is limited due to the heat development
***
continues transmit time is limited due to the heat development
****
the maximum allowed output power is typically reached at an input power of 2W PEP ,
*****
high operating voltage and peak input drive power, this setting may violate other operating
conditions. if the nominal RF-Power exceeded by 1dBm, the PA will switch into the bypass mode.
Overdriving the PA leads to the harmonic distortion exceeding the permitted limits.
The PA switches to bypass mode when the maximum output power is exceeded by 1 dBm.
The maximum output power is achieved with a matched antenna. If the antenna is not
matched, tune the antenna to the right impedance with the integrated antenna tuner.
