Phase Locked Oscillators Internal Ref. APL -
02 Series


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

The APL - 02 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 with an internal crystal 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. The PLOs also have a reference monitor output. DRO types have an external tuning screw for factory set up only.
