What effect does temperature have on the frequency stability and service life of mobile phone shielding equipment?
1. The parameter indicators of all devices will change with the change of temperature. If the temperature is too high, the stability of the device will be affected. For example, when a shielded area has signals on both sides of the interference frequency band, the jammer is usually effective. When the temperature rises, the frequency occurs. If the deviation is large, the interference frequency deviates from the original working frequency, which makes the original shielding lose its effect or causes the shielding effect to be good or bad.
2. The temperature affects the service life of the equipment. The usual rule is that the service life is inversely proportional to the square of the temperature increase. For example, when the chip temperature of a certain device is 65°C, the mean time between failures is 100,000 hours; when the temperature rises to 115°C, the mean time between failures is 30,000 hours.
