Phase Locked Coaxial Resonator Oscillators
CAES' series of phase locked coaxial resonator oscillators has been designed for use in commercial and military systems where demanding performance, high reliability and cost are critical.
This family of products take advantage of low phase noise transistors and a metalized high Q coaxial resonator. When phase locked to an external crystal reference, the low noise characteristics of the high Q resonator are enhanced by the long term stability of the external reference.
The series PCRO can be custom configured to meet the demanding electrical performance and environmental requirements for military airborne, radar and communications applications.
Features such as low phase noise, high power, small size and low cost make CAES' PCRO product line the best value on the market today.
