Capacitive sensor device, and radio device with a capacitive sensor device and method for adjusting a transmission power of a radio device

摘要

Capacitive sensor device for a radio device, for estimating a specific absorption rate (sar) of the radio device, wherein the sensor device with at least one first electrode (el1) is coupled, and wherein in the operation of the radio device (10) the first electrode (el1) at the same time a sensor electrode of the capacitive sensor device and an antenna (a) of the radio device, and wherein the first electrode (el1)– via a high-pass filter with a transceiver - circuit of the radio device, and– via a low-pass filter with the sensor deviceis coupled.
