If b2 exceeds a1, it indicates circuit gain; S11 is known as the return loss, or how much power is reflected from the transmitter to an antenna. Each parameter is typically characterized by magnitude, decibel and phase.
SParameters OPTIMAL CONNECTIVITY UAE
These are still complex values and are related to the forward and reverse voltages at each of the.
Which s parameter is equivalent to forward gain?
S21 is the forward transmission coefficient that indicates the gain of the amplifier. I(x) = v+(x) z0 − v−(x) z0 amplitude, not rms values. If smaller, it implies a loss. Therefore, s 21 is the forward gain.
**the correct answer is:** **c. In the case of s21, which signifies forward gain, a comparison is made between b2 and a1.
