Hi, Aaron.
Quote:If you are just talking about the transistor, then yes..
Yes, I was talking about transistor. In cascode LNA, I see that the overall Gm will be gm*Q with Q quality factor of input circuit.
Is that another way that you imply?
Quote:In the first place, is the mixer integrated on the same chip as the LNA?
Yes.
Quote:If so, then its unlikely that your mixer input impedance is 50-ohm.
Well, may I know why? I thought that it is a standard that applies to both on and off chip mixers.
Quote:Adding a transformation network would be one option. You also have a transformation network at the input.
Are the other options? I am curious to know that.
Quote:I'm not really sure what you mean. if you label two wires the same name, then they are considered to be connected, and current can flow between them...
I didn't express it well. To label a wire, we only need to press "L" and then place it on the wire that we want to label.
I am wondering if there is a similar method/way to do that with current. If so, it is great. I want to rename current points by meaningful names.
