Abstract: A radio frequency (RF) front-end system and a method for reducing interference are provided. The RF front-end system includes a processing circuit, a first transceiver, an RF front-end circuit, and a first antenna. The RF front-end circuit includes a first switch circuit, a first filter circuit, and a second switch circuit. The first switch circuit and the second switch circuit respectively include first signal paths and second signal paths. The first filter circuit includes an all-pass circuit corresponding to a first frequency band and a first channel filter corresponding to a first frequency channel. The processing circuit executes an anti-interference process, including: switching to the all-pass circuit; executing a channel sounding process to determine usage statuses of a plurality of channels; executing an automatic channel selection process to select a target channel; and switching to the target channel, and controlling the first transceiver to perform signal transmission.

Abstract: An electronic device includes a substrate, at least one electronic element and a heat dissipating electromagnetic shielding structure. The heat dissipating electromagnetic shielding structure is disposed on the substrate and covers the at least one electronic element, wherein the heat dissipating electromagnetic shielding structure includes a shielding frame and a heatsink. The shielding frame includes a plurality of spring members. The spring members are bent toward the substrate and partially abut against the heatsink. When the heatsink and the shielding frame are correspondingly arranged, a shielding space is defined, the electronic element is disposed in the shielding space, and a heat generated by the at least one electronic element is conducted out of the shielding space via the heatsink.
