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