Crystek’s new CVCO55CXT-4812-4812 Coaxial Resonator Oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler. The CVCO55CXT family’s frequency doubling, 2X fundamental technology reaches new performance levels of lower phase noise and much lower harmonics over the competition, while achieving lower current consumption in the process.
The oscillator operates at 4812 MHz with a tuning voltage range of 0.3 Vdc to 4.7 Vdc. This coaxial VCO features a typical phase noise of -102 dBc/Hz @ 10KHz offset and has good linearity. The CVCO55CXT-4812-4812 CRO exhibits an output power of 3.0 dBm typ. into a 50 ohm load with a supply of +5.0 Vdc and a current consumption of 25 mA (max.).
Engineered and manufactured in the USA, the CVCO55CXT-4812-4812 CRO is packaged in the industry-standard 0.5-in x 0.5-in package. Pushing and Pulling are both minimised to 1.5 MHz/V and 0.5 MHz, respectively. Second harmonic suppression is -30 dBc typical.
The CVCO55CXT-4812-4812 has been developed for use in applications such as digital radio equipment, fixed wireless access, satellite communications systems, and base stations.
