I have some questions about the LT5538 behavior @ 2.14GHz
When Pin =-75dBm, what's the value of output voltage?
When Pin < -75dBm, what's the value of output voltage?
The output voltage will vary from part to part. But it generally settles to around 0.35V which is the starting voltage for levels below <-75dBm.
The Vout at -75dBm is where it starts to increase, may be slightly higher than the starting voltage, around 0.4V or so, again will vary from part to part.
Noted and thank you!
