In modern communication systems, accuracy and stability matter. Whether it’s satellite communication, radar, or signal processing, the quality of the oscillator used can make or break the system. That’s where low phase noise oscillators come in. These devices play a crucial role in minimizing signal disruptions and maintaining system reliability.
At Princeton Microwave, we understand how essential clean signal generation is. Our goal is to offer dependable solutions for applications that demand high performance. That’s why our crystal oscillators with low phase noise are trusted across industries.
In this blog, we’ll explore why low phase noise matters, how crystal oscillators work, and how our solutions meet the demand for stability and precision.

What Is Phase Noise?
Phase noise refers to the frequency instability of an oscillator. It shows up as small random fluctuations in the phase of a signal. These fluctuations may seem minor, but they can lead to significant problems in high-performance systems.
A cleaner signal—meaning lower phase noise—means better resolution, accuracy, and less interference. That’s why phase noise is one of the most important specifications when evaluating an oscillator.
How Crystal Oscillators Work?
Crystal oscillators are electronic circuits that use a quartz crystal to create a precise frequency. The crystal vibrates at a fixed frequency when a voltage is applied. This vibration acts as a timing reference for generating electrical signals.
The structure is simple, but the output is powerful. Crystal oscillators are widely used because they offer high frequency stability and precision.
The key to performance lies in how clean the output signal is. That’s where phase noise comes into play. A high-quality oscillator produces minimal noise around its central frequency.
Why Low Phase Noise Matters?
Low phase noise isn’t just a feature—it’s a necessity in critical applications. Systems that rely on precision timing or signal clarity can fail without it.
Here’s why it matters:
- Improved Signal Clarity: Cleaner signals mean better data transmission.
- Better System Performance: Reduced phase noise improves the resolution in radars and imaging systems.
- Lower Error Rates: In communication systems, phase noise can cause bit errors and reduce reliability.
- Enhanced Detection Capabilities: In defense or aerospace systems, lower noise can reveal hidden signals.
When every microsecond counts, low phase noise becomes a deciding factor in system success.
Applications That Depend on It
Many industries rely on low phase noise oscillators to keep their systems accurate and efficient. These include:
- Telecommunications: For clean data transmission and low bit-error rates.
- Aerospace and Defense: Where signal integrity affects mission success.
- Medical Equipment: In imaging tools, where high resolution is critical.
- Test and Measurement: Where equipment must detect very fine variations.
- Navigation Systems: To ensure reliable GPS signals and timing accuracy.
Across all these fields, low noise means high trust.
