Hi all,
I am trying to model the Schottky diode SMS 7630-079 LF for rectifier application in ADS for a frequency of 5.8 GHz. The data sheet provides absolutely no information apart from the basic parameters and the artwork of the diode. After a little bit of research, I got the Fig.1 as shown, from a research article from IEEE Microwave Magazine.
In addition, I found out the S-parameters provided by the manufacturer on the website. I modelled the diode model as per Fig.1. and compared with the diode spice model provided by the manufacturer. The comparison is shown in Fig. 2. The red curves represent the values provided by manufacturer. The blue curves represent the values I obtained after modelling in ADS
Though the S parameters look to be in-line with each other, the impedance curves show a wide discrepancy. Especially, at 5.8 GHz, this is a major issue. I understood that I needed to include the bond inductance and capacitance values in addition. But, I am unable to get these values. Please help me in resolving this issue.
