Crystek’s CVCO55CC-1690-1690 voltage-controlled oscillator (VCO) operates at 1,690 MHz with a control voltage range of 0.3 V to 4.7 V. This VCO features a typical phase noise of -120 dBc/Hz at 10 KHz offset and has excellent linearity. Output power is typically +2.5 dBm. The VCO R...

Crystek’s CVCO55CC-1690-1690 voltage-controlled oscillator (VCO) operates at 1,690 MHz with a control voltage range of 0.3 V to 4.7 V. This VCO features a typical phase noise of -120 dBc/Hz at 10 KHz offset and has excellent linearity. Output power is typically +2.5 dBm. The VCO – both engineered and manufactured in the U.S. – is packaged in the industry-standard 0.5-inch x 0.5-inch surface-mount package. Input voltage is 5V, with a maximum current consumption of 25 mA. Pulling and pushing are minimized to 1.0 MHz and 0.5 MHz/V, respectively, while the oscillator operates over a temperature range of -40 °C to +85 °C. Second harmonic suppression is -15 dBc (typical).

The CVCO55CC-1690-1690 is aimed at applications such as digital radio equipment, fixed wireless access, satellite communications systems, and base stations.
