Measurement Circuits
4.5.1
Gain (G
V) measurement in LOW band
Figure 12
Gain (G
V) measurement in LOW band
Z
i >> 50 => Vi = 2 x Vmeas = 80 dBV
V
i = Vmeas + 6dB = 80 dBV
V
0 = V’meas + 16 dB (transformer ratio N1:N2 and transformer loss)
G
v = 20 log(V0 / Vi)
4.5.2
Gain (G
V) measurement in MID and HIGH bands
Figure 13
Gain (G
V) measurement in MID and HIGH bands
V
i = Vmeas = 70 dBV
V
0 = V’meas + 16 dB (transformer ratio N1:N2 and transformer loss
G
v = 20 log(V0 / Vi) + 1 dB (1 dB = insertion loss of balun)
