Semtech Corp. has expanded its PerSe product portfolio with the introduction of a purpose-built chipset for 5G mobile devices. The PerSe Connect SX9376 5G chipset is designed to optimize RF performance, enhance connectivity and support compliance with global specific absorption rate (SAR) standards for 5G-enabled consumer devices, said the company.

The PerSe technology senses human proximity and enables end devices to implement advanced radio frequency (RF) control, said Semtech, enabling automatic adjustment of system-level RF emissions, which allows connected devices such as smartphones, tablets and laptops to operate at peak performance, while maintaining compliance.
The SX9376 SAR sensor addresses the challenge of adding more RF antennas to 5G-enabled products to meet the frequency increase, which makes it more challenging for designers to maintain global compliance and accurately manage the devices’ RF power, according to the company.
The SX9376 chipset offers a maximum of eight sensor inputs to support multiple antennas and simplify the sensor design. It is also compatible with various antenna designs, which makes it easy to integrate into the latest 5G mobile devices, said Semtech.
Key specs include a capacitance resolution down to 0.74aF, capacitance offset compensation up to 600 pF and an operating temperature range of -40°C to 85°C. It also features advanced temperature correction to minimize false triggers caused by noise and temperature as well as ultra-low power consumption.
The SX9376 is housed in a 1.8 × 1.9 × 0.55-mm QFN package.
