We consider the complex Ginzburg-Landau equation with two pure-power\nnonlinearities and a damping term. After proving a general global existence\nresult, we focus on the existence and stability of several periodic orbits,\nnamely the trivial equilibrium, bound-states and solutions independent of the\nspatial variable. In particular, we construct bound-states either explicitly in\nthe real line or through a bifurcation argument for a double eigenvalue of the\nDirichlet-Laplace operator on bounded domains.\n
