Background technique

With the development of terminal technology, the internal structure of the terminal becomes more and more complex, which causes interference between circuits corresponding to functional modules of the terminal, thereby affecting the performance of the functional modules. For example, a global positioning system (Global Positioning System, GPS) of the terminal is a signal receiving circuit, and its center frequency is 1575.42 MHz and the bandwidth is 2 MHz. The low frequency (Low Band, LB) Long Term Evolution (Long Term Evolution, LTE) circuit has a transmit frequency range of 699MHz-915MHz. Therefore, the second harmonic of individual frequency bands of LTE LB will just fall within the GPS band, thus interfering with the GPS. performance.

In the related art, in order to reduce interference between different modules, filter circuits are added on different modules to filter out interference signals. For example, filter circuits are respectively set in the above-mentioned LTE LB circuit and GPS circuit, so that the second harmonic generated by the LTE LB circuit is filtered out in the LTE LB circuit, and the received fundamental wave generated by the LTE LB circuit is filtered out in the GPS circuit, Thereby reducing interference to GPS.
