Wireless communications test

Block diagram

Overview

Wireless communication test equipment (WCTE) use configurable radio frequency (RF) front end to test wireless devices to ensure compliance with multiple standards. Our integrated circuits and reference designs help you create a WCTE signal chain that has a high level of integration and low power as channel count increases.

Design requirements

    Modern wireless communications test designs require:

  • Direct RF sampling data converters with wide bandwidth and high dynamic range.
  • Low-jitter multichannel JESD204B-compliant clock distribution.
  • Efficient power supply that minimizes board area and improves thermal performance.
  • Low EMI power supply that improves system sensitivity and dynamic range.
