Oscillator using magnetostatic surface wave delay line

摘要

An oscillator for operation in the frequency range from about 2 GHz to at least 18 GHz using a magnetostatic surface wave delay line as a frequency control element in a feedback loop connected around an amplifier. The oscillator is tunable by varying the magnetic field intensity at the magnetostatic surface wave propagating medium and by varying the distance between input and output rf couplers along the propagation surface.
