The influence of temperature on the frequency stability and service life of mobile phone signal shielding equipment

The mobile phone signal jammer device scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as the phenomenon of searching the network, mobile phone no signal, no service system and so on.

The influence of temperature on the frequency stability and service life of mobile phone signal shielding equipment
1. The parameter indicators of all devices will change with temperature changes. Excessive temperature will affect the stability of the device. For example, when a shielded area has signals on both sides of the interference frequency range, the shielding is usually effective, and the frequency will occur when the temperature rises. Larger deviation, the interference frequency deviates from the original working frequency, which makes the original shielding lose its effect or cause the shielding effect to go up and down from time to time.

2. Temperature affects the service life of the equipment. The general 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 at 115°C, the mean time between failures is 30,000 hours.
