What Does HBAR Stand For?

HBAR stands for High Overtone Bulk Acoustic Resonator

HBAR, or High Overtone Bulk Acoustic Resonator, is a precision device used in advanced frequency control and timing applications. It exploits the resonance of bulk acoustic waves at high overtone frequencies, enabling superior performance in terms of stability, temperature coefficients, and size. These characteristics make HBARs ideal for use in telecommunications, aerospace, and high-frequency electronic circuits, where reliable timing and signal purity are critical.
