ACOUS

Ultra precise acoustic wave resonators for defense communications

Our resonator technology makes military communication devices smaller, lighter, and more power-efficient — with cleaner, more secure signals.

The Problem

Current oscillators are holding back military communications

Oscillators generate the stable signal used for communication — acting as a precise clock that keeps the system synchronized. They are inside every military radio, radar system, and communication satellite.

Current oscillators need extra stabilization circuits, which means more power consumption. Larger components mean bulkier radios and shorter battery life. For a soldier in the field, this translates to heavier gear, less operational time, and degraded signal quality when it matters most.

Our resonator produces a cleaner, more stable signal at the source — reducing the need for extra circuitry, lowering power consumption, and enabling smaller, more efficient radios.

Technology

Up to 10x higher signal quality than today's commercial resonators

Today's commercial acoustic resonators achieve a Quality Factor (Q) of 2,000–10,000 — but they leak energy, signals drift, and phase noise is high. ACOUS targets a Q of 50,000+, delivering dramatically cleaner and more stable signals. The result: smaller radios, lower power consumption, and more reliable military communications.
