VCO Cuts Noise At 3850 MHz

Feb. 24, 2014
A voltage-controlled oscillator provides excellent spectral purity at a center frequency of 3850 MHz.

Designed for operation at 3850 MHz, model CVCO55CC-3850-3850 is a voltage-controlled oscillator (VCO) that typically draws 35 mA current from a +8-VDC supply. It is supplied in an industry-standard surface-mount SMD package measuring 0.5 × 0.5 in. and delivers +7 dBm typical output power at 3850 MHz. Typical tuning sensitivity is 7 MHz/V for a tuning range of 0.5 to 4.5 V. The typical phase noise is -110 dBc/Hz offset 10 kHz from the carrier and -132 dBc/Hz offset 100 kHz from the carrier, while second harmonics are typically -15 dBc. Pushing is typically 0.2 MHz/V, while pulling is typically 1 MHz peak to peak. The oscillator is designed for operating temperatures from -40 to +85°C.
