Making Mixer Measurements
High Dynamic Range Swept RF/IF Conversion Loss
Figure 2-20 shows the conversion loss of this low-side LO mixer with output filtering.
Notice that the dynamic range from the pass band to the noise floor is well above the
dynamic range limit of the R Channel. If the mixer under test also contained
amplification, then this dynamic range would have been even greater due to the
conversion gain of the mixer.
