6.8 Channel-to-Channel Crosstalk

Crosstalk is defined as the ratio of the signal at the drain pin (Dx) of a different channel, when a signal is applied

at the source pin (Sx) of an on-channel. The characteristic impedance, Z0, for the measurement is 50 Ω. Figure

6-8 shows the setup used to measure, and the equation used to compute crosstalk.

6.9 Bandwidth

Bandwidth is defined as the range of frequencies that are attenuated by less than 3 dB when the input is

applied to the source pin (Sx) of an on-channel, and the output is measured at the drain pin (Dx) of the device.

The characteristic impedance, Z0, for the measurement is 50 Ω. Figure 6-9 shows the setup used to measure

bandwidth.
