Features and Benefits

  • Self contained board, including the ADF5902 24 GHz VCO PGA, with integrated 2-channel PA output and fractional-N frequency synthesizer with ramp generation
  • Windows-based software allows control of the ADF5902 functions from a PC
  • Externally powered by a 5 V power supply

Product Details

The EV-ADF5902SD1Z evaluation board allows the user to evaluate the performance of the ADF5902 24 GHz voltage controlled oscillator (VCO) programmable gain amplifier (PGA) with a 2-channel PA output and ramping phase-locked loop (PLL). Figure 1 shows the EV-ADF5902SD1Z evaluation board, which contains the ADF5902, three high frequency K type subminiature version A (SMA) connectors for the local oscillator (LO) output, two transceiver (TX) outputs, banana connectors for the power supply, and a connector for the serial interface.

The EV-ADF5902SD1Z evaluation board requires an EVAL-SDP-CS1Z system demonstration platform serial (SDP-S) controller board, which the kit does not include. The EVAL-SDP-CS1Z SDP S allows software programming of the ADF5902 device.

Full specifications on the ADF5902 are available in the ADF5902 data sheet.Consult the data sheet in conjunction with this user guide when working with the EV-ADF5902SDIZ evaluation board.

The Windows®-based PLL Software provides easy programming of the synthesizer.
