Phase Locked Oscillators Internal TCXO Ref.
APL - 04 Series

  • 300MHz to 14GHz
  • +/-1ppm Stability -20 +70C
  • Fundamental Frequency (CRO or DRO)
  • Small Size
  • Low Phase Noise
  • Low Microphonics
  • Low Current
  • Internal Voltage Regulator

The APL - 04 series of fundamental frequency phase locked oscillators utilise coaxial resonators (CRO) to 3GHz and dielectric resonators (DRO) to 14GHz in a phase locked loop with an internal TCXO reference. Circuit design uses SMT devices including Si bipolar active devices up to 3GHz and GaAs FET active devices above 3GHz. 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.
