Semtech launches new chipset for 5G mobile devices

1 min read

Semtech has expanded its PerSe product portfolio with the release of a new integrated circuit (IC) that’s been purpose-built for 5G mobile devices.

PerSe technology is able to sense human proximity and enables end devices such as smartphones to implement advanced radio frequency (RF) control. According to Semtech, the PerSe Connect SX9376 will enable designers to optimise RF performance, enhance connectivity and support elevated compliance with global specific absorption rate (SAR) standards for 5G-enabled consumer devices.

These intelligent sensors from Semtech enable automatic adjustment of system level RF emissions allowing connected devices – smartphones, tablets, hotspots, and laptops – to operate at peak performance while, at the same time, maintaining compliance.

“As the evolution of the consumer device market continues to accelerate, OEMs will continue to deliver connected devices that take advantage of the best available technologies to deliver the highest levels of performance, connectivity, and battery life that consumers demand,” said David Wong, senior director of consumer sensing products for Semtech’s Advanced Protection and Sensing Products Group.

By 2030, the global 5G market is expected to grow at a 47.6% compound annual growth rate (CAGR) with a market valuation of $198.44 billion.  To bring these 5G-enabled products to market, OEMs are having to add more RF antennas into the design to address the frequency increase. The additional antennas can make it challenging for OEMs to address global SAR compliance and accurately manage the device’s RF power.

To address this, Semtech’s SX9376 has a maximum of 8 sensor inputs to support multiple antennas and simplify the sensor design without compromising performance and regulation. Semtech’s new chipset is also compatible with various antenna designs, making it easy to integrate into the latest 5G mobile devices.

Key benefits of the SX9376 in smartphones:

  • The PerSe Connect 9376 enables optimisation of system RF performance to enhance connectivity and support global SAR compliance;
  • A maximum of eight sensor inputs to support multiple antennas;
  • Best-in-class sensing performance with high-resolution analogue front end (AFE) down to 0.74aF;
  • Extreme versatility to support antenna designs with up to 600 pF capacitance;
  • Superior robustness with advanced temperature correction to minimize false triggers caused by noise and temperature; and
  • Single-chip, fully integrated solution to support all SAR sensing needs.
