Crystek CVCO55CXT-5370-5470 Coaxial Resonator Oscillator (CRO)

The Crystek CVCO55CXT-5370-5470 Coaxial Resonator Oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler. The CVCO55CXT family’s frequency doubling, 2X fundamental technology achieves good performance levels of lower phase noise and lower harmonics, while achieving lower current consumption in the process.

The CRO operates from 5370 to 5470 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 @ 10KHz offset and has good linearity. The CRO exhibits an output power of 0.0 dBm typ into a 50 Ω load with a supply of +5.0 VDC and a current consumption of 30 mA (max).

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 device is suitable for use in applications such as digital radio equipment, fixed wireless access, satellite communications systems and base stations.
