The ADF5709 wideband, monolithic microwave integrated circuit (MMIC), voltage controlled oscillator (VCO) supports an output frequency (fOUT) range of 9.85 GHz to 20.5 GHz while maintaining ?83 dBc/Hz phase noise at 100 kHz offset without subharmonic tones. The wide frequency tuning range and low phase noise allow phase-locked loop (PLL) solutions for a variety of frequency bands and limit the need for multiple narrow-band VCOs. The broad frequency coverage reduces the board design complexity and simplifies the bill of materials when designing RF and microwave applications.The VCO operates from a single 5 V supply and consumes only 70 mA of supply current that results in minimal power dissipation. The ADF5709 low power consumption is ideal for high performance applications with limited or no airflow. The monolithic construction of the VCO allows optimal output power and noise characteristics over temperature variations.The VCO is fully integrated and incorporates a resonator, a negative resistance device, and a varactor diode that minimize the number of external components and reduces board space.The low input impedance on the VTUNE pin of the ADF5709 enables high tuning speed and modulation bandwidth, which allows faster frequency sweeps and lock times when used as part of a frequency synthesizer, for example, in radar or in test and measurement applications.The ADF5709 is encapsulated into a tiny, 3.90 mm ? 3.90 mm, RoHS compliant, ceramic leadless chip carrier (LCC) package. The package includes through vias to the exposed pad, enhancing thermal characteristics.The small size, optimal noise performance, low power consumption, and wide tuning range of the ADF5709 make the device ideal for many applications requiring flexibility, high performance, a small footprint, and a tight power budget. The ADF5709 is pin to pin compatible with the HMC733 and other Analog Devices, Inc., wideband VCOs.APPLICATIONSIndustrial and medical equipmentTest and measurement equipmentMilitary radars, electronic warfare (EW), and electronic countermeasures (ECMs)Point to point and multipoint radiosVery small aperture terminals (VSATs)Wireless communication infrastructure
