Coplanar Traveling Wave Amplifier
The example documented here is a three stage Trawling Wave Amplifier. The schematic of the circuit is shown in Figure 9-13. It shows the use of coplanar discontinuities with airbridges. The layout of the circuit is shown in Figure 9-14. Figure 9-15 shows some details of this layout with the used FET. The simulated S-Parameters of the circuit are plotted in Figure 9-16. A gain of nearly 7dB could be achieved.
