ADLsimRF "power backoff"

Hi Everyone,

 

 

I am using ADLsimRF software for my RF chain. I know that Pout backoff means that the input signal power is high so that it is saturating the block in the RF chain; but I faced a situation in which I think its not saturating the block while the block is turning red in ADLsimRF indicates that it is saturated!

 

 

The block (ADL5602)specifications are:

 

 

Power Gain = 19.5 dB

 

Output P 1dB = 19.3 dBm

 

 

input signal power = -8 dBm

 

 

So output signal power is 11.5 dBm

 

 

which is less than 19.3 dBm ; so why the block is turning red indicating 7.8 dB of Pout Backoff?

 

 

Thanks
