Hello,I need to make my M1-0616 mixer in a phase detector, so phase difference between RF and Lo will be transformed into phase detector.
However there is a certain dinamic range for the mixer in which it can act as a phase detector as shown below.
The IF port acts by transforming the phase difference of LO and RF into IF?

My LO input power is 10dB, accroding to the the table.
What is the allowed RF input power allowed so the mixer wont get compressed?
What is the RF and LO power law for good phase detection between them?
If I put 10dBm on RF and LO then I am afraid the mixer will be compressed.
How to configure RF and LO ports properly for this purpose?
Thanks.

Embrace compression/saturation, don't avoid it when using a diode ring DBM as a phase detector. Have at least 5 dBm (= 1 dB compression point) and up to 10 dBm at the RF port with the LO being at 10 dBm. The IF DC error voltage should only depend on the phase relationship between RF and LO and not be at the mercy of the exact power applied at the RF port.

As for the termination of the IF-port and because of the very high frequencies involved, you could use a suitable, commercial bias-tee as a diplexer. Terminate the bias-tee with a good 50 Ohm load. Terminate any remaining RF components at the DC-port of the bias-tee also with 50 Ohm and the DC component with a higher value resistor (around 500 Ohm, but up for experimentation) to maximize the sensitivity of the detector.
