Coaxial-based VCO with an internal frequency doubler

March 04, 2013 // By Jean-Pierre Joosting
Crystek’s latest CVCO55CXT-5270-5375 coaxial resonator oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler. The oscillator family’s frequency doubling, 2x fundamental technology offers higher performance levels of lower phase noise and much lower harmonics over the competition, while achieving lower current consumption in the process.

The CVCO55CXT-5270-5375 operates from 5270 to 5375 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. The CRO exhibits an output power of 0.0 dBm typical into a 50 ohm load with a supply of +5.0 Vdc and a current consumption of 30 mA (maximum).

Engineered and manufactured in the USA, the device 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.

Typical applications include digital radio equipment, fixed wireless access, satellite communications systems, and base stations.
