VCOs with electrical tuning at 8 to 12 GHz
The electrical tuning option for the DRO operating at 10 GHz has a control range of 0 to 12 Vdc, providing ultra-fine tuning precision. The electrical tuning provides ±3 MHz of frequency control allowing the oscillator to be quickly and easily phase-locked.
DRO Series oscillators provide a low phase noise and an exceptional spectral purity as good as -110 dBc/Hz, typically, at 10 kHz from the carrier. DROs minimize power consumption by operating off a 5 Vdc bias while drawing only 20 mA, typically, and are available in a surface mount packages measuring 0.91 x 0.91 x 0.40 inches. For rugged applications, DROs are available in a connectorized metal enclosure measuring 1.25 x 1.25 x 0.85 inches.
In addition to the superior phase noise performance and electrical tuning advantage, the oscillators deliver 0±3 dBm of output power into a 50 ohm load. DROs are designed to operate over the industrial temperature range of -40 to 85°C making them a good fit for the toughest environmental applications.
These devices will enhance any PLL control system due to their low tuning sensitivity figure of approximately 1 MHz/V. The DRO Series oscillators have second harmonic attenuation of better than -25 dBc. The pushing specification for the 10 GHz DRO is less than 1 MHz/V within a 5% change of the supply voltage while pulling is less than 2 MHz with a 12 dB return loss, any phase.
