Proximity Sensor Minimizes RF Exposure In Next-Gen Handhelds

Proximity Sensor Minimizes RF Exposure In Next-Gen Handhelds
Semtech Corp.

Capable of distinguishing a human body from other objects, the SX9306 proximity sensor minimizes radio-frequency (RF) exposure by selectively reducing radio-frequency power in mobile phones and tablets. The low-power, capacitive proximity sensor employs a smart engine for human body detection and advanced specific absorption rate (SAR) control. SAR is the measure of the amount of RF power that is radiated into the human body when in a close proximity to a mobile device. Other features include a 2.7V to 5.5V input supply voltage, up to four capacitive sensor inputs, capacitive sensing down to 0.08 fF, capacitance offset compensation up to 30pF, and an operating temperature range from -40°C to +85°C. The SX9306 is available in two packages, a 3 mm x 3 mm thin QFN or a 1.63 mm x 1.23 mm WLCSP. Pricing is $0.72 each/1,000 for QFN packages. A full datasheet is available at
