Phase Locked Oscillators External Ref. APL - 03 Series

  • 300 MHz to 14 GHz
  • Fundamental Frequency (CRO or DRO)
  • External Reference
  • Small Size
  • Low Phase Noise
  • Low Microphonics
  • Low Current
  • Custom Design

The APL - 03 series of fundamental frequency phase locked oscillators utilise coaxial resonators (CRO) to 3GHz and dielectric resonators (DRO) to 14 GHz in a phase locked loop for use with an external reference. Circuit design uses SMT devices including Si bipolar active devices up to 3 GHz and GaAs FET active devices above 3 GHz. The output contains a buffer amplifier for improved ruggedness, higher output power and a wider range of load VSWR. DRO types have an external tuning screw for factory set up only.

Frequencies above 14 GHz are available - please contact us for more information.

Phase Noise (dBc/Hz) (typical)
Offset Frequency (Hz) Output Frequency (GHz)
0.6 1.5 3.0 4.0 10.0 14.0
100 Reference Dependent - See Notes
1K Reference Dependent - See Notes
10K Reference Dependent - See Notes

1M -140 -140 -135 -135 -120 -115

Reference Frequency Notes:
The output frequency must be an integral multiple of the reference frequency.
Reference level required 0+/-3dBm.
At offset frequencies up to 100Hz, the output phase noise is degraded from that of the reference oscillator by approximately 20logN+3dB, where N is the ratio of the output to the reference frequency.
