Product Details

The ADF5901 is a 24 GHz Tx monolithic microwave integrated circuit (MMIC) with an on-chip, 24 GHz VCO with PGA and dual Tx channels for radar systems. The on-chip, 24 GHz VCO generates the 24 GHz signal for the two Tx channels and the LO output. Each Tx channel contains a power control circuit. There is also an on-chip temperature sensor.

Control of all the on-chip registers is through a simple 4-wire interface.

The ADF5901 comes in a compact 32-lead, 5 mm × 5 mm LFCSP package.

View Detailed Evaluation Kit Information

The EV-ADF5901SD2Z evaluation board allows the user to evaluate the performance of the ADF5901 24 GHz VCO and PGA with a 2-channel PA output. Figure 1 shows the EV-ADF5901SD2Z, which contains the ADF5901, the ADF4159, three high frequency, K-type SMA connectors for the local oscillator (LO) output and two transceiver (Tx) outputs, two high frequency SMA connectors for the AUX and the AUX outputs, banana connectors for power supply, and a connector for the serial interface.

The EV-ADF5901SD2Z evaluation kit also contains software that is compatible with Windows XP and later versions to allow easy programming of the device.

The EV-ADF5901SD2Z evaluation board requires an EVALSDP-CS1Z (SDP-S) controller board, which is not supplied with the kit. The EVAL-SDP-CS1Z allows software programming of the ADF5901 device.

Full specifications on the ADF5901 are available in the ADF5901 data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.

Features & Benefits

Contains ADF5901 24 GHz VCO and PGA with a 2-channel PA output
Contains ADF4159 13 GHz fractional-N frequency synthesizer

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.

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.
