What effect does temperature have on GPS jammers?

When a mobile phone is in use, it works within a specific frequency range, establishes a connection with a base station through radio waves, and transmits data and sound according to a specific baud rate and modulation method. The cell phone jammer scans the frequency range from the low end to the high end of the forward channel at a specific speed. This scanning speed will cause garbled interference to the signal received by the mobile phone, making it impossible for the mobile phone to detect the normal data sent by the base station, resulting in the mobile phone being unable to establish a connection with the base station, and there will be phenomena such as searching for the network, no signal, and no service.

Let’s discuss the impact of temperature on the stability and service life of GPS jammers.

Temperature affects the parameters of all devices, including GPS jammer. Higher temperatures have a negative impact on the stability of the device. For example, when there are signals in the interference frequency band on both sides of the shielded area, the normal shielding function is effective. However, as the temperature increases, the frequency may change significantly, interfering with the original operating frequency. This may result in the loss of the expected shielding effect or varying degrees of change in effectiveness.

Temperature changes also affect the service life of the device. Generally speaking, the service life is inversely proportional to the square of the temperature increase. For example, assuming that the chip temperature of a device is 65°C, its mean time between failures is 100,000 hours. If the temperature rises to 115°C, the MTBF drops to 30,000 hours. This shows that the increase in temperature leads to a shortened equipment life.
