World-class performance and innovative design characterize Wenzel Associates as the leader in low phase noise crystal oscillators, synthesizers and frequency related modules. Wenzel Associates has become a leader in low noise under vibration through extensive work with special custom crystals, vibration isolation systems and phase locking techniques for high system integrity under extreme environments.

The typical MXO is comprised of Wenzel’s VHF Ultra Low Noise OCXO integrated with several low noise multiplier stages.

Multiplied Crystal Oscillator MXO Series

  • 200 MHz to 12 GHz
  • Exceptional Phase Noise
  • Excellent Spectral Purity
  • Phase Locked
  • High Output Power
  • VHF & Multiplied Output

 

MXO-FR MXO - Free Running
Used when a stand alone Ultra Low Noise frequency source is required.

MXO-PLD Phase Locked with Dividers
Frequency dividers are used to prescale the External Reference and the internal VHF Crystal Oscillator to phase lock at a low frequency.

MXO-PLM Phase Locked with Multipliers
Frequency multipliers are used to multiply the External Reference up to phase lock at the internal VHF Crystal Oscillator frequency.

MXO-PLMX Phase Locked to Internal OCXO
The Internal VHF Crystal Oscillator is phase locked to Internal HF Crystal oscillator for improved stability and close to carrier phase noise.
