Overview

Wide output frequency range: 9.85 GHz to 20.5 GHz
Wide tuning bandwidth
Low single sideband phase noise: −83 dBc/Hz at 100 kHz offset

No external resonator needed
Supply current: 70 mA typical at V_CC = 5 V
24-terminal, 3.90 mm × 3.90 mm, ceramic LCC package

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 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 V_TUNE 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.

Product Details

The EV-ADF5709 evaluates the performance of the ADF5709 wideband, voltage controlled oscillator (VCO). Figure 1, found in the user guide, shows a photograph of the EV-ADF5709. The EV-ADF5709 contains the ADF5709, external supply headers, supply decoupling capacitors, a VTUNE Subminiature Version A (SMA) connector, and a 2.92 mm, RF output K connector. No software interface is required to control the ADF5709 while the device is operating as a standalone VCO in open-loop mode.

For full details on the ADF5709, see the ADF5709 data sheet, which must be consulted in conjunction with the user guide when using the EV-ADF5709.

Product Details

The EV-ADF41513SD1Z and EV-AD41513SD2Z are evaluation boards that can be used to evaluate all the features of the ADF41513. The EV-ADF41513SD1Z requires an external voltage controlled oscillator (VCO). The EV-ADF41513SD2Z includes an on-board 10 GHz to 20 GHz HMC733 VCO. The EV-ADF41513SD3Z instead includes the ADF5709 9.85GHz to 20.5GHz VCO and also has a reduced voltage regulator count.

EV-ADF41513SD1Z has Subminiature Version A (SMA) connectors to connect the charge pump output (VTUNE) to the tuning input of the VCO and the phase-locked loop (PLL) radio frequency (RF) input (RFIN) to the VCO output.

Both variants of the evaluation board include the ADF41513 frequency synthesizer, 100 MHz reference (crystal oscillator (XO)), loop filter, universal serial bus (USB) interface, low noise voltage regulators, and a USB cable to connect the board to a PC USB port

For easy programming of the synthesizer, download the Windows®-based software from the ADF41513 product page at www.analog.com/ADF41513. The file transfer program (FTP) user name and password are printed on the label inside the lid of the evaluation board box.

The evaluation board requires a SDP-S (Figure 4), which is not included with the kit. The SDP-S allows software programming of the ADF41513 device through a USB interface. Consult the ADF41513 data sheet in conjunction with this user guide when working with the evaluation boards.
