AD8313 detector output with periodic pulse output

A phenomenon was discovered when testing with AD8313 chip recently. When there is interference from mobile phone signals, the chip will output a periodic pulse signal, which will last for a few minutes and then disappear instantly. If the mobile phone is used again for interference, this pulse phenomenon will appear again. This phenomenon can occur when the chip is powered by a battery or a linear power supply. I don't know where to improve the test.
