Crystek CVCO55CXT-4812-4812 coaxial resonator oscillator (CRO)

Crystek’s 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 provides low phase noise and low harmonics while achieving lower current consumption.

The CVCO55CXT-4812-4812 operates at 4812 MHz with a tuning voltage range of 0.3 to 4.7 VDC. This coaxial VCO features a typical phase noise of -102 dBc/Hz @ 10 kHz offset and has good linearity. The CVCO55CXT-4812-4812 CRO exhibits an output power of 3.0 dBm typ into a 50 Ω load with a supply of +5.0 VDC and a current consumption of 25 mA (max).

The CRO is packaged in the industry-standard 0.5 x 0.5″ 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 CRO is suitable for use in applications such as digital radio equipment, fixed wireless access, satellite communications systems and base stations.
