Hello , I have two signals with 90 degree phase between each other going into the IF.
What is the output of the RF signal of HMC8193?
Thanks.

UPDATE:
Hello,I am reading the mathematical derivation manual shown below.
In the red arrow that is a situation where we have two signals on the same frequency.
How its possible that two signals could stay individual on the same frequency.
on every frequency we have amplitude and phase .
I know the I/Q diagrams but its too abstract.
I cant understand how there is an amplitude and phase on a certainfrequency and it canhide inside two combined signals?
Thanks.

UPDATE:
If input this signal into netwrk analizer i cannot see that it consists of two different signal.
