Cellular Base Station


The increased amount of data and video being transmitted via the cloud has placed huge bandwidth and power demands on the entire infrastructure market. The combination of a wide range of bias control DCPs, voltage references, digital converters, and highly integrated and industry-proven timing tree solutions addresses the needs of these modern systems.

Target applications include base station radio cards, remote ratio units, baseband units, satellites, and microwave communication links.

Key Features

  • Lowest phase noise, which maximizes signal-to-noise ratio from converters and enables the best radio performance
  • Broad frequency range allows design portability to support existing 4G and future 5G standards as well as mmWave massive MIMO radios
  • Extremely low skew drift capability, making it ideal for beamforming applications
  • State-of-the-art solutions for 5G, with up to 18GHz LO output frequency with leading phase noise, low phase skew drift for AAS/beamforming, and cTE < 5ns for network equipment
