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?
