Abstract : Use of high overtone bulk acoustic resonators (HBAR) has made possible development of low phase noise multiple frequency microwave sources operating directly at microwave frequencies. Most recently a low noise source has been developed at L-band which provides signals at approximately 5-MHz intervals and achieves phase noise suppression equivalent to sources based on low frequency quartz crystal stabilization and multiplication. The direct microwave HBAR multiple frequency source requires a fraction of the hardware required to achieve the same phase noise suppression for multiple microwave frequency operation by any other means.
