I would like to use AD8302 to design a reflectometer at 2.4GHz. According to the datasheet page 17, the input impedance can be approximated by a shunt resistor in parallel with a capacitor. I want to use the circuit of reflectometer as shown in figure 13 page 20, I which matched the circuit with 50 Ohm system.
If I understand correctly, in one port matching, according to figure 13 in datasheet, I have to accounted for R1, C1, C4, and the internal capacitor 10 pF all connected with the shunt resistor in parallel with a capacitor as input interface approximation. Does it corrects?
