A microwave oscillator containing a GaAs amplifier, a rnagnetostatic spin wave (MSW) signal-to-noise enhancer (SNE) used as a nonlinear transmission line, directional couplers, and a variable attenuator has been designed and investigated. It was shown, that nonlinearity of the SNE and amplifier resulted in a bistability in the system : two different levels of oscillation power correspond to one attenuator setting. The oscillator was switched on under action of external short low power microwave pulses.
