Phase Locked Dielectric Resonator Oscillators

Our PLDRO series delivers high-performance microwave signal generation by combining a precision PLL digital IC with a high-Q dielectric resonator oscillator (DRO). This hybrid architecture enables excellent frequency stability, spectral purity, and ultra-low phase noise for demanding RF applications.
Supporting C-, X-, Ku-, and Ka-band operation from 7 GHz to 30 GHz, the PLDRO provides reliable, low-noise signal sources for next-generation microwave systems. It supports both external reference input and integrated OCXO options, offering flexibility for synchronised or standalone operation.
With ultra-low phase noise and low spurious performance, the PLDRO ensures high signal integrity in critical microwave environments.

Applications: NewSpace and LEO satellites, Radar and electronic warfare systems, Defence and aerospace platforms, SATCOM terminals and transceivers, Microwave test and measurement equipment.

Country of origin: France and India.
