Figure 1a. Test circuit of the 0.5GHz production test board used for NF, Gain and OIP3 measurements. This circuit achieves a trade-off between optimal NF,
Gain, OIP3 and input return loss. Circuit losses have been de-embedded from actual measurements.
Figure 1b. A diagram showing the connection to the DUT during an S-parameter and Noise parameter measurement using an Automated Tuner System.
