Abstract: Recent developments in the study of the nonlinear microwave properties of high temperature superconducting thin films are reviewed. The typical non-linear dependence of the surface impedance of such films on frequency, temperature and microwave power is described. Various possible sources of the nonlinearity are surveyed and problems that need to be solved are also discussed.
