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.

Applications

  • Automotive radars
  • Industrial radars
  • Microwave (µW) radar sensors
