Overview

The EVAL-ADF5902 evaluation board allows the user to evaluate the performance of the ADF5902, a 24 GHz transmitter (Tx) monolithic microwave integrated circuit (MMIC) with an on-chip, 24 GHz voltage controlled oscillator (VCO). The VCO features a fractional-N frequency synthesizer with waveform generation capability, programmable grid array (PGA), and dual transmitter channels for radar systems. The on-chip 24 GHz VCO generates the 24 GHz signal for the two transmitter channels and the local oscillator (LO) output. Each transmitter channel contains a power control circuit. There is also an on-chip temperature sensor.

Features:

  • 24 GHz to 24.25 GHz VCO (ISM band)

  • 2-channel 24 GHz power amplifier with 8 dBm output

  • Single-ended outputs with mux and mute function

  • Programmable output power

  • LO output buffer

  • High and low speed FMCW ramp generation

  • 25-bit fixed modulus allows subhertz frequency resolution

  • Auxiliary 8-bit ADC

  • Power control detector

  • ±5°C temperature sensor

Applications:

  • Automotive radars

  • Industrial radars

  • Microwave radar sensors

Recommendations

People who follow the flow that is outlined, have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone forums, but before that, please make sure you read our documentation thoroughly.

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
