CRO Generates 2950-MHz Signals

April 28, 2014

A surface-mount CRO provides stable output signals at 2950 MHz.

Designed for a stable output frequency of 2950 MHz, model CVCO55CC-2950-2950 is a voltage-controlled coaxial-resonator oscillator (CRO) that provides at least +5 dBm output power and typically +7 dBm output power at that frequency. It offers tuning sensitivity of 7 MHz/V across a tuning range of 0.5 to 4.5 VDC for use in such applications as phase-locked-loop (PLL) synthesizers. The phase noise offset 10 kHz from the carrier is typically -115 dBc/Hz while the phase noise offset 100 kHz from the carrier drops to -135 dBc/Hz. Harmonics are typically -15 dBc. The 50-Ω CRO, which typically draws 30 mA from a +8-VDC supply, features an operating temperature range of -40 to +85°C. It is supplied in a surface-mount-device (SMD) package measuring 0.5 × 0.5 in. (12.7 × 12.7 mm).
