6525-MHz coaxial resonator oscillator delivers lower phase noise

January 02, 2013 // By Paul Buckley
Crystek's latest CVCO55CXT-6525-6525 coaxial resonator oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler.

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-6525-6525 operates at 6525 Mhz with a tuning voltage range of 0.3 Vdc to 4.7 Vdc. This coaxial VCO features a typical phase noise of -100 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 +8.0 Vdc and a current consumption of 35 mA (maximum).
