(Mixer design) IFp and IFn have same phase

[Ata_sa16]

1) I used 2.6Ghz and 2.4Ghz for obtaining 200Mhz IF signal.

2) Using pss and pac analysis observed the gain.

**broken link removed**

3) I put filter in the output and got the 200Mhz IF signal.

Please fix the attachment, I cannot see the picture? I want to design the fRF = 2.5 GHz, fLO = 5 GHz (fRF = fLO/2).

Generally mixer is designed for down conversion. So you down convert a Ghz to IF signal which has like 200Mhz frequency.

In your case, you have a LC tank as your load so you havr to tune it for 2.5Ghz. But i dont understand,in which application you are going to use this mixer.

That's the project in class. In fact, fRF=2.5GHz, fLO=4.9GHz, so fIF=2.4GHz
