hi

what is the relationship between the voltage gain of amplifier2 and its s21 parameter??

what value of s21 gives a voltage gain of 3dB?

thanx

S21=dbpolar(3,0)

This will give you a gain of 3 dB with a phase of zero degrees. This is a polar format for the complex number so the arguments of the dbpolar function are magnitude in dB and angle (phase) in degrees.
