I want to obtain a DC output value by using the same two frequencies as the RF and LO signals in the mixer. I am trying to create a mixer and check the properties of this mixer,
but I have the following questions. I want to obtain factors such as P1dB, IIP3, and NFdsb.
Do I need to put the RF and LO signals at the same frequency even during these simulations? Or should I put in different frequencies to find out their performance? (ex. 2.4GHz & 2.41GHz)
If LO and RF signals are input at the same two frequencies, the result is strange. Taking NF as an example, the noise becomes larger on the DC side, so the value close to DC showed a value of about 52 dB. The value is strange. In this situation, is it okay to put LO and RF signals equally?
