Product Details

The ADF5904 is a 4-channel, 24 GHz, receiver downconverter. Each channel contains a single-ended RF input with an on-chip balun followed by a differential low noise amplifier (LNA) and a downconverter mixer with differential output buffers. The RF LO path also has an on-chip balun.

Control of the on-chip registers is through a simple 3-wire interface.

The ADF5904 comes in a compact 32-lead, 5 mm × 5 mm LFCSP package.

View Detailed Evaluation Kit Information

The EV-ADF5904SD2Z evaluation board allows the user to evaluate the performance of the ADF5904 24 GHz receiver downconverter. Figure 1 shows the board, which contains the ADF5904, five high frequency SMA connectors for the local oscillator (LO) input, four receiver (Rx) inputs, eight SMA connectors for the baseband outputs, banana connectors for power supply, and a connector for serial interface.

The evaluation kit also contains software that is compatible with Windows^® XP and later versions to allow easy programming of the device.

This evaluation board requires an EVAL-SDP-CS1Z SDP-S board (not supplied with the kit). The SDP-S board allows software programming of the ADF5904 device.

Full specifications on the ADF5904 are available in the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.

EVAL-RADAR-MMIC

View Detailed Evaluation Kit Information

The EV-RADAR-MMIC2 evaluation board is designed to evaluate the performance of the ADF5901, a 24 GHz transmitter (Tx) monolithic microwave integrated circuit (MMIC); the ADF5904, a 24 GHz receiver (Rx) MMIC; and the ADF4159, a 13 GHz phase-locked loop (PLL) for a frequency modulated continuous wave (FMCW) radar system.

The EV-ADAR-D2S adapter board contains the eight AD8129 differential receiver amplifiers that convert the baseband ADF5904 differential signals to single-ended signals with a 20 dB gain.

The evaluation kit also contains the Analog Devices EV-RADAR-MMIC Software, which is compatible with Windows^® XP and later Windows versions to allow easy programming of the device.

The EV-RADAR-MMIC2 evaluation board requires an SDP-S or SDP-B board (not supplied with the kit). The SDP board allows software programming of all the devices.

Full specifications for the ADF5901, ADF5904, and ADF4159 are listed in the ADF5901 data sheet, the ADF5904 data sheet, and the ADF4159 data sheet available from Analog Devices and should be consulted in conjunction with UG-866 when using the evaluation board.

Features & Benefits

Evaluates the chipset containing the ADF5901 24 GHz Tx MMIC, the ADF5904 24 GHz Rx MMIC, and the ADF4159 13 GHz PLL
Accompanying software controls all functions from a PC

EVAL-TINYRAD

View Detailed Evaluation Kit Information

The EV-TINYRAD24G is a radar evaluation module that allows the implementation and testing of radar sensing applications in the 24 GHz industrial, scientific, and medical (ISM) band. The EV-TINYRAD24G uses frequency modulated continuous wave (FMCW) radio signals and an integrated antenna array in a multiple input multiple output (MIMO) radar scheme. The combined antennas, similar to digital beamforming (DBF), allow the TINYRAD module to detect the distance, speed, and angular position of multiple targets simultaneously. The raw analog-to-digital converter (ADC) data is forwarded by the onboard Blackfin^® ADSP-BF706 digital signal processor (DSP) to the PC. The PC evaluation software, with an included graphical user interface (GUI), performs radar signal processing steps to yield radar point clouds that can be visualized as range doppler or range angle plots. The radar algorithms are also available as MATLAB^™ and Python^™ code and enable quick development of user defined, application specific code.
