ADF5709

Voltage Controlled Oscillator by Analog Devices

Note : Your request will be directed to Analog Devices.

The ADF5709 from Analog Devices is a wideband MMIC Voltage Controlled Oscillator that operates from 9.85 to 20.5 GHz. 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. It exhibits -83 dBc/Hz phase noise at 100 kHz offset without subharmonic tones. The monolithic construction of the VCO allows optimal output power and noise characteristics over temperature variations. The VCO operates over a 5V DC power supply and delivers an output power of up to 4 dBm while consuming 70 mA (typical) of current.

The VCO is available in a 24 terminal ceramic LCC package that measures 3.90 x 3.90 mm and is suitable for 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), and wireless communication infrastructure applications.

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.
