4-5 2-Port Amplifier Measurement
VNA Measurements
The 5 kHz low end of the MS20xxC VNA Master facilitates the characterization of low
frequency resonances that are commonly caused by bias networks. The screen-captured
measurement that is illustrated in
Figure 4-11
shows the difference between an amplifier
with proper low frequency biasing (TR1) and one with a defective bias inductor (M1).
