Low-Noise VCO Tunes 5685 to 5780 MHz

March 4, 2015
A low-noise VCO tunes from 5685 to 5780 MHz for applications in digital radios.

Model CVCO55CXT-5685-5780 is a voltage-controlled oscillator (VCO) that tunes from 5685 to 5780 MHz by merit of a control voltage range of +0.3 to +4.7 VDC. The oscillator achieves typical phase noise of -102 dBc/Hz offset 10 kHz from the carrier with 0-dBm typical output power. Supplied in a 0.5 × 0.5 in. surface-mount SMD package, the VCO controls second-harmonic levels to typically -30 dBc and exhibits pulling of 0.5 MHz and pushing of 1.5 MHz/V. The source is well suited for wireless access, digital radios, satellite-communications (satcom) systems, and cellular base stations. Typical current consumption is 25 mA from a +5 VDC supply.
