Abstract

The embodiment of the present application discloses a radio frequency front-end circuit and a tracker, which relate to the field of antennas. The RF front-end circuit includes a first antenna and a second antenna. The first antenna is used as a diversity antenna for receiving high-frequency signals and a main antenna for receiving intermediate frequency signals. The second antenna is used as a diversity antenna for receiving intermediate frequency signals and a main antenna for receiving high-frequency signals. Antenna, the first antenna receives the main frequency signal and diversity high frequency signal from the base station, the second antenna receives the main frequency signal and diversity medium frequency signal from the base station, and the transceiver receives the high frequency signal and low frequency signal through the diversity receiving mode Signal, which can improve the quality of cellular network signals at high and low frequencies, and improve the accuracy of cellular network positioning.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a radio frequency front-end circuit and a tracker. Background technique [0002] The tracker is used to notify the user of its own position through one or more of cellular network positioning, GPS positioning, WLAN positioning or Bluetooth positioning, and is suitable for application scenarios such as personal positioning, vehicle positioning, pet positioning or valuables positioning. The tracker has the characteristics of small size and light weight. Generally, the built-in antenna is used to receive satellite navigation signals, WLAN signals and cellular network signals. The interference between each signal is relatively large, and the signal quality is not good. How to improve the signal quality of the tracker? Quality is an urgent problem to be solved at present. Contents of the invention [0003] The embodiment of the present application provides a radio frequency front-end circui...
