Abstract:
1. A traveling wave switch comprising: a coplanar waveguide line structure formed by a first metal layer, a second metal layer, and a signal line, providing a switching channel for signals passing through the traveling wave switch; and a field effect transistor composed of a gate, a drain, and a source, wherein the drain is electrically connected to the signal line, and the signal line directly passes through the drain of the field effect transistor, the source is electrically connected to a ground of the coplanar waveguide line structure, the gate is connected to the first metal layer through an air bridge, and connected to the gate by passing the ground of the coplanar waveguide line structure through a mesa resistor, and is used to switch the signals passing through the traveling wave switch; wherein the ground of the coplanar waveguide line structure is the second metal layer.
