ADS Schottky Diode Non linear model for Mixer.
I need to design a single balanced mixer at K band using shottky diodes.
I have find some available diodes, to use at this frequencies such as: Skyworks DMK2790
In the Data sheet there is a SPICE model parameter (Fig. 5 table 3)
In ADS I created a file with the model in Fig 5, an i n a PN-junction diode model included all parameters from SPICe model, except Td, that I didn't know where to include it in ADS.
I plotted IV curve, and it is ok, but i tried doing S parameters, and it doesn't varies with frequencies. So something it's Ok. I thought the SPICe model will be engough to have a non-linear model.
So my questions are (many):
- Td parameter in SPICE is equivalent to something in ADS?
- SPICE parameters is not a non linear model?
- What I need to do to modelize the diodes in order to start looking about the impedance the diode presents at each frequency?
Please, I need some help.
