I am hard to find the value for impedance matching in ADS
my circuit is
1. receive 13.96MHz freq AC signal ( source impedance = 50ohm )
2. then through rectifier ( AC signal -> DC signal )
3. then through regulator ( ?V DC singal -> 5V, 1A DC signal )
when simulating in ADS, there is some problem
#1. I don't know how to put regulator device into simulator ( like LM7805 )
#2. because of problem #1, I can't specify Load impedance, so I don't know input impedance of Rectifier with regulator, so I can't specify matching circuit.
#3. if I know only 7805's impedance value, without putting regulator device into simul, I can put resistance having same value with 7805's resistance.
Pleas help me.

More than 7V is required.
Use constant current of 1A as load of rectifier.
If possible, use nonlinear current source which ramps up from 0A at 6~7V to constant 1A.
Here use SDD(Symbolically Defined Device) or Verilog-A.
Yes.
can you recommend the diode in rectifier at freq, 13.96MHz?
I find some shottkey diode,, like 1n5817, 1n5819
