Coaxial Resonator Oscillator Cuts Noise at 3.5 GHz

June 2, 2015

This compact coaxial resonator oscillator features low phase at a carrier frequency of 3500 MHz.

Model CVCO55CCQ-3500-3500 is a coaxial resonator oscillator designed for use at 3500 MHz. It operates on tuning voltages of +0.3 to +4.9 VDC with tuning sensitivity of 8 MHz/V, delivering +6 dBm output power that remains flat within ±2 dB. The oscillator features typical phase noise of -115 dBc/Hz offset 10 kHz from the carrier and -135 dBc/Hz offset 100 kHz from the carrier. Second harmonics are no worse than –8 dBc. The oscillator draws 27 mA current from a supply voltage of +5 ±0.25 VDC and is built for an operating temperature range of -40 to +85°C. It is supplied in a surface-mount housing measuring 0.50 × 0.50 in. (12.70 × 12.70 mm).
