Low Phase Noise Oscillators
Greenray utilizes unique design techniques that focus on low phase noise and tight frequency stability over temperature and offer excellent long-term characteristics for use in communications and defense applications.
The Importance of Low Phase Noise
Phase noise is a measure of the spectral purity of a signal and can be a critical attribute for many systems and applications. Phase noise is defined as noise power in a 1Hz bandwidth, at a particular frequency removed from the carrier, and the phase noise of the crystal oscillator can impact overall system performance.
In communications systems, phase noise of the local oscillator in a transmitter or receiver can cause the signal spectrum to spread out and leak into adjacent channels, causing noise and interference. Digital systems experience the effects of phase noise in the time domain, as jitter. Jitter will affect the digital modulation quality, resulting in increased bit error rates. High performance radar systems rely on the detection of extremely faint return signals from the target, and these signals can be easily masked by phase noise of the receiver's local oscillator. Selecting the appropriate low phase noise crystal oscillator is vital to ensuring overall system and application performance and reliability.
