  • Integrated PLL, transmitter, receiver, Baseband, and ADC.
  • 76- to 81-GHz coverage with 4 GHz available bandwidth.
  • Four receive channels.
  • Three transmit channels.
  • Ultra-accurate chirp engine based on fractional- N PLL.
  • TX power: 12 dBm.
  • RX noise figure:.
  • 14 dB (76 to 77 GHz).
  • 15 dB (77 to 81 GHz).
  • Phase noise at 1 MHz:.
  • 95 dBc/Hz (76 to 77 GHz).
