use these lines

.ac lin 100 .5e9 7e9
.net v(5) vin rin=50 rout=50
.print ac s11(db) s21(db) s22(db) s12(db) zin(r) zin(i) zout(r) zout(i)
.plot ac s11(db) s21(db) s22(db) s12(db) zin(r) zin(i) zout(r) zout(i)

where 5 is the output node , vin is the input voltage , input and outputs are matched with 50 ohm resistances( it depends on ur application ) , frequency is varied using .ac command

deepak.
