Digital I/Q Imbalance correction IP for Wireless Applications

Overview

The IQE 100 is a wideband imbalance correction IP, that digitally match in-phase and quadrature signal paths in radio architectures employing complex demodulators such as direct down-conversion receivers. The IQE 100 IP core is available as FPGA IP and as a GDSII macro block.

Key Features

  • Digital IQ balancing for complex frequency demodulation
  • Long Term Evolution (LTE) Advanced compatible
  • Self-calibrating background operation
  • 20 to 50 dB added image attenuation
  • Wideband image suppression over 100 MHz bandwidth

Benefits

  • Improves RX signal quality
  • Relaxes AFE requirements
  • Enhances RX sensitivity
