Matching of diode impedence in Mixer design

[zeshan102]

how to measure the diode on and off resistance in ADS and which resistance is used to match the coupler if this diode is used for mixer.

Hi,

I think you will need to find the matching circuit using nonlinear model for the diode and HB simulator.

i think you can use the large-s parameter method

Hi,

Could I know what you mean by the large s-parameter method?

Thanks.

here is a paper for your reference...

Hello guys,
I've done the same project b4 in ads, u can simply use any HB simulation controller, in my case i ve used LSSP (large signal s-parameters) & it worked effeciently, but u ve first to perform a nonlinear modeling of the diode used.


good luck :wink:
