Summary A specialized type of traveling‐wave field‐effect transistor, the gate and drain lines of which have composite right‐ and left‐handed structures, is considered as the platform to support nonlinear oscillatory waves. The cubic–quintic complex Ginzburg–Landau equation is obtained by application of the reductive perturbation method, by which we quantify the homogeneous oscillations including the property of the Andronov–Hopf bifurcation point, oscillation frequency, and amplitude. Several numerical calculations follow to validate the Ginzburg–Landau equation‐based analysis. Finally, the dynamics of numerically obtained stationary flat‐top pulses are discussed.
