Off isolation is defined as the ratio of the signal at the drain pin (Dx) of the device when a signal is applied to the source pin (Sx) of an off-channel. The characteristic impedance, Z0, for the measurement is 50 Ω. Figure 39 shows the setup used to measure off isolation. Use off isolation equation to compute off isolation.
