NOTES: A. CL includes probe and jig capacitance.
B. A 50-Ω termination resistor is needed to match the loading of the network analyzer.
Figure 8. Test Circuit for Off Isolation (O_IRR)
OFF isolation is measured at the output of the OFF channel. For example, when V_SEL = GND and A₁ is the input,
the output is measured at 1B₂. All unused analog input (A) ports are connected to ground, and output (B) ports are
left open.
