Embodiment Construction
[0032] Such as figure 1 As shown in the present disclosure, a device for detecting terminal power in a positioning system includes an antenna 1 , a low noise amplifier 2 , a filter module 3 , a frequency shift module 4 , an analog-to-digital conversion module 5 and a logic processing module 6 .
[0033] Antenna 1 is used to receive the air interface signal sent by the terminal;
[0034] The low-noise amplifier 2 is connected to the antenna 1, and the antenna 1 sends the received air interface signal to the low-noise amplifier 2, and the low-noise amplifier 2 performs low-noise amplification on the air interface signal. Specifically, the low-noise amplifier 2 is usually provided with two low-noise amplifier channels, one as the main channel and the other as a bypass. The low-noise amplifier 2 has a saturation threshold. When the air interface signal exceeds the saturation threshold, the air interface signal is passed into the Bypass for low-noise amplification, otherwise, the ...
