What is a value of local frequency for mix1 and mix2 ?
wccheng wrote on Aug 30th, 2008, 8:01am:I have combined all together and run the PSS + PXF in order to get the overall voltage gain.
It gives the M-shape voltgae gain and the voltage different is 10dB.
Just does it show gain including image response of mixer ?

Do you evaluate this using PSS/PXF with same simulation condition as total combination ?
Although you see gain including image response in total combination, you don't see image response in Rx chain ?
