DRO / PDRO

Panda Microwave customized up to 40GHz low phase noise (DRO or PDRO) , Phase Locked Dielectric Resonator Oscillators (PDRO) take advantage of the small size, low phase-noise and high efficiency, including PDRO and DRO.
Phase Locked Dielectric Resonator Oscillators (PDRO) are used widely in today’s electronic warfare, radar and communication systems. They find use both Commercial and Military communication systems where demanding performance, high reliability and cost are critical. The phase locked oscillators utilize ceramic coaxial resonator and ceramic dielectric resonator fundamental frequency sources with low phase noise performance. The design of the Phase Locked Oscillators is based on sampling phase detector technology, which provides the comparison frequency at the same frequency as the fundamental frequency output.
