(Calibrated P
) was obtained. Obtaining the real external
current of the circuit we also need the value of the amplifier’s
input impedance (R
dBm
). The values of the input impedances of
the amplifier were measured by network analyzer and given in
Table 1 (R
amp
amp
(Ohm)). The external voltage of the circuit (V
)
was calculated by Equations 4-6 expressing how those values
were obtained.
