Wireless communication infrastructure

The low input impedance on the V_TUNEpin 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.

GENERAL DESCRIPTION

The ADF5709 wideband, monolithic microwave integrated

circuit (MMIC), voltage controlled oscillator (VCO) supports

an output frequency (f_OUT) 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 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 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 ADF5709 is pin to pin compatible with the HMC733 and

other Analog Devices, Inc., wideband VCOs.

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.
