Hello ,there is a component as shown below,in which it could be used as phased detector as shown in the data sheet below.
based on the data sheet , i put my inputs at LO and RF inputs and IF is my phase detector (DC) output.
on one hand they say that maximal input power is 21dBm
on the other table they say that we have an IP3 compression at 0dB.
I am confused.
What is the proper input power for this mixer used as a phased detector?
