Crystek’s CVCO55CXT-5685-5780 Coaxial Resonator Oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler. The family’s frequency doubling, 2X fundamental technology is asserted to reach new performance levels of lower phase noise and much lower harmonics over the competition, while achieving lower current consumption in the process. The CVCO55CXT-5685-5780 operates from 5685 MHz to 5780 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 CVCO55CXT-5685-5780 CRO exhibits an output power of 0.0 dBm typ. into a 50-Ohm load with a supply of +5.0 VDCand a current consumption of 25 mA (max.). The CRO is packaged in the industry-standard 0.5-in x 0.5-in package. Pushing and Pulling are both minimized to 1.5 MHz/V and 0.5 MHz, respectively. Second harmonic suppression is -30 dBc typical. Applications include digital radio equipment, fixed wireless access, satellite communications systems, and base stations.
