What applications would benefit from an SPXO with Low Phase Noise properties?
Phase noise can be defined as the short term, random fluctuations in the oscillator’s frequency domain. For some applications maximum clarity and low phase noise is critical. Such applications include: Wireless communications, radar systems, test & measurement, high‑speed data communications such as DAB, fibre-optic networks, and GNSS receivers, including GPS, GLONASS, Galileo and BeiDou systems.
In fact, any application that demands precise frequency control, high signal quality, and low interference can benefit from the use of low phase noise oscillators.
IQD's portfolio of products includes SPXOs, TCXOs, OCXOs and Rubidium Oscillators with exceptional low phase noise performance.
