Overview

Our integrated circuits and reference designs help you create longer range and lower power wireless communications modules for the best possible network performance in diverse geographies.

Design requirements

Modern wireless communication systems require:

  • Higher speed networks that supply real-time data to utility providers.
  • Standards-based systems that are interoperable across vendors.
  • Reliable performance in environments with strong interference from radio frequency (RF) noise.
  • Power-efficient hardware and firmware that extend battery life.

Power supply

close

Wireless communications modules sometimes need to integrate their own power supply rather than rely on power delivered from the host meter. Low power consumption is always crucial. A boost converter to efficienctly source higher current levels during transmission may be required dependent on output power requirements.
