passive mixer match for input and outpout---help

[steven_l]

how can i do match input and output match for a resisitive mixer?

RF signal is a broadband signal


here is my circuit:

50 Ohm source---50 Ohm input match---mixer---50 Ohm output match---filter---50Ohm load


As the resistive mixer has only 4 mosfet which act as switch, the input impedance is time-variant.

How can i estimate the impedance?

And another question:

How can i du math work with Candece? Use PSS+PSP analysis or SP ayalysis?

Who can upload useful file?


Thank you .

If you use Cadence Spectre, use PSS/PAC or PSS/PSP.

But I don't use PSS/PSP.
I use Agilent ADSsim's HB-SS or Cadence Spectre's PSS/PAC.
