QuSine provides opto‑electronic microwave oscillators and signal generators that deliver ultra‑low phase‑noise and jitter‑free RF signals across 3 GHz – 60 GHz. Leveraging optical frequency division and high‑speed photodetectors, its bench‑top units achieve phase‑noise as low as –154 dBc/Hz at 10 GHz and jitter down to 6 fs, with configurable output power from –20 dBm to +13 dBm. These specifications support precise clock distribution, radar timing, and carrier generation for 5G/6G, satellite, and high‑performance radar applications.

Problem
High-performance RF and microwave systems require signal sources with ultra‑low phase noise and jitter, but conventional electronic oscillators struggle to meet the stability needed for emerging 5G/6G networks, satellite radar, and precision timing applications.
Solution
QuSine delivers opto‑electronic microwave oscillators and signal generators that combine photonic stability with electronic tunability to produce ultra‑low noise RF signals across a wide frequency range (3 GHz – 60 GHz). By leveraging optical frequency division and high‑speed photodetectors, the devices achieve phase‑noise levels as low as –154 dBc/Hz at 10 GHz (100 kHz offset) and jitter down to 6 fs from 1 kHz to 100 MHz. The product line offers selectable output powers from –20 dBm to +13 dBm, a 6 MHz loop bandwidth, and a compact bench‑top form factor with touchscreen control. These specifications enable precise clock distribution, low‑jitter radar timing, and stable carrier generation for next‑generation communication and space‑borne sensing systems.
Target Audience
Primary customers are RF system designers, satellite and radar manufacturers, and telecom equipment providers developing 5G/6G infrastructure that demand ultra‑stable microwave sources.
