This tutorial has two parts (read
through the whole tutorial before
you start):
•How to use S-parameter data
file in ADS
The diode
has S-parameters that are measured (in our case) or given in the Spec
sheet. To simulate the
Diode, you
will use a 2-port Data element. To make
the diode detector, you will add a capacitor.
To match the
diode detector, you will need to make a single stub matching network on the
front.
Then you
will simulate to get the S-graphs and
find the Zin. This will tell you how
the circuit should
work.
2. Generation of Layout
In order to
solder the capacitor and diode to the board, you will use solder pads. You will choose a
Different
diode that has the same case size as the one we are using, and place that with
its solder pads.
You will
also place solder pads for the capacitor.
Now you can no longer simulate the performance
Of the
circuit. This is just for layout and
milling.
