A new type of microwave source is developed by utilizing the sideband where the modulation instability of magnetostatic surface wave takes place. It is found that separation between magnetic gamet film and metallic ground plane and the film thickness affect the operation characteristics of the device. Generation of higher microwave fiequency and the operation bandwidth of the device can be controlled by a biasing magnetic field. The experimental results are in accordance with the theoretical predictions.
