Phase Lock Oscillator


Phase Lock Oscillator – Engineered for consistent performance

The Orbital Research Phase Locked Oscillator (PLO) is designed for communications systems requiring extremely accurate timing. High modulation and coding techniques (ModCods) require extremely low phase noise. The Orbital Research PLO phase locks to the station’s 10 MHz reference, reduces system phase noise, and filters out any extraneous signals.

This allows a 10 MHz station reference to be distributed to non-collocated equipment like modems and up-and-down converters while maintaining or enhancing the station clock phase noise. This PLO is perfect for applications that require all equipment to use the same reference clock but require that clock to be distributed without phase noise degradation.

The device comes with a 2-port 10 MHz built-in splitter for easy distribution to equipment.

Key advantages: 

  • One station clock can be replicated across complex, large systems
  • Maintain signal strength despite system challenges
  • Build a well-timed system
  • Reduce phase noise
  • Customize phase noise for different networks
  • Know the status of your system, real-time from anywhere in the world
  • Distribute the output of two or more devices when you have more than one converter
  • Worry-free stable signal if your other clock goes down
  • Plug and Play for easy installation
  • Reliable signal through for higher order ModCods
  • Immune to humidity and wet weather conditions
  • Minimizes EMI radiation to ensure it does not become an antenna
  • Anodized case prevents oxidization

Perfect for applications that require all equipment to use the same reference clock, but require that clock to be distributed without phase noise degradation.




  1. Gateways or Teleports that already have a station clock, but need enhanced Phase Noise performance for higher order ModCods
  2. Gateways or Teleports that need to provide distributed reference signals near the antenna that are locked to an existing station clock due to distance or signal strength issues
  3. Terminals that require a stable back-up (standby) reference in case of primary failure – Orbital PLO provides a stable reference signal in free running mode
