CRO tips frequency doubling for low phase noise, harmonics

Crystek Corp. debuts a coaxial resonator oscillator (CRO) with an internal proprietary frequency doubler. The CVCO55CXT-6900-6900 coaxial-based voltage-controlled oscillator (VCO) offers lower phase noise and much lower harmonics at lower current consumption.

The CVCO55CXT-6900-6900 operates at 6,900MHz with a tuning voltage range of 0.5Vdc to 4.5Vdc. This coaxial VCO features a typical phase noise of -100dBc/Hz @ 10kHz offset and has good linearity. The CVCO55CXT-6900-6900 CRO exhibits an output power of 2.0dBm typ. into a 50Ω load with a supply of +8.0Vdc and a current consumption of 35mA (max.).

Engineered and manufactured in the USA, the CVCO55CXT-6900-6900 CRO is packaged in the industry-standard 12.7mmx12.7mm package. Pushing and Pulling are both minimized to 1.5MHz/V and 0.5MHz, respectively. Second harmonic suppression is -30dBc typical.

The CVCO55CXT-6900-6900 is suited for applications such as digital radio equipment, fixed wireless access, satellite communications systems,and base stations.
