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.
