ADAR1000 - X Band and Ku Band Beamformer

Description

The ADAR1000 is a 4-channel, X and Ku frequency band, beamforming core chip for phased arrays.

This device operates in halfduplex between receive and transmit modes.

In receive mode, input signals pass through four receive channels and are combined and output at the common RF_IO pin.

Features

  • 8 GHz to 16 GHz frequency range.
  • Half-duplex for transmit and receive modes.
  • Single-pin transmit and receive control.
  • 360° phase adjustment range.
  • 2.8° phase resolution.
  • ≥31 dB gain adjustment range.
  • ≤0.5 dB gain resolution.
  • Bias and control for external transmit and receive modules.
  • Memory for 121 prestored beam positions.
  • Four.
  • 20 dBm to +10 dBm power detectors.
  • Integrated temperature sensor.
  • Integrated 8-bit ADC for power de.
