Low Phase Noise (PDRO)

Low phase noise dielectric resonator oscillators (PDROs) designed for microwave, radar, communication and frequency synthesis applications, delivering excellent spectral purity, frequency stability and low phase noise performance.

kTB Low Phase Noise (PDRO)

The PDRO50L and PDRO57L are ultra-compact, low-phase-noise Dielectric Resonator Oscillators (DROs) designed for high-frequency RF/microwave applications. The PDRO50L operates from 1–16 GHz, while the PDRO57L extends coverage to 1–44 GHz, making them ideal for systems requiring wideband performance. Both models deliver ≥10 dBm output power with exceptional phase noise as low as -174 dBc/Hz @1 MHz (PDRO50L at 1 GHz) and -148 dBc/Hz @1 MHz (PDRO57L at 10 GHz).

Featuring internal or external reference options, robust harmonic suppression (≥60 dBc), and a compact footprint (e.g., PDRO50L: 50.8×47.8×15.7 mm), these oscillators balance precision, power efficiency, and reliability for demanding environments.



The General Applications:

  • Satellite Communication: Stable signal generation for transponders and high-frequency transceivers.
  • Radar and EW Systems: Low-noise frequency sources for phased-array radar and electronic warfare (EW) applications.
  • Test & Measurement: Calibration of spectrum analyzers, vector network analyzers, and millimeter-wave test setups.
  • Aerospace and Defense: Critical systems requiring ultra-low phase noise, such as navigation and SIGINT platforms.
  • Broadband Wireless: High-frequency signal synthesis for 5G, mmWave, and beyond.
