Hi,
I am looking for ADS/Spice model of macom varactor diode model MA46H071/MA46H201. In the manufacturer website only the ADS model of MA46H120 is available. I do have the datasheets of all those varactor diodes from their website. But I am looking for a way/suggestion about how can I create an ADS or spice models of the MA46H071/MA46H201 models?
Thank you in advance.
The varactor diode is a pn junction diode which is used as a voltage variable capacitance. It is operated in the reverse bias mode. If you have the C-V curve, then you can get CJ0 = the varactor diode at zero bias,
The grading coefficient m which is =0.5 for the abrupt p-n junction
The expression fitting the C-V curve is given by
C= Cj0/ ( 1 + VB/PHI)^m,
VB is the bias voltage and PHI is the built in voltage.
So, you can fit the C-V by the expression given above
The SPICE parameters are Cj0, PHI and m
