7.7 Bandwidth

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

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

The characteristic impedance, Z0, for the measurement is 50Ω. Figure 7-7 shows the setup used to measure

bandwidth.
