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 CVCO55CXT-4812-4812 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 at 10 kHz offset and has good linearity. It exhibits an output power of 3.0 dBm typical into a 50 ohm load with a supply of +5.0 Vdc and a current consumption of 25 mA (maximum).

The VCO is packaged in the industry-standard 0.5-inch x 0.5-inch package. Pushing and pulling are both minimized to 1.5 MHz/V and 0.5 MHz, respectively. Second harmonic suppression is -30 dBc typical.

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