A multi-frequency tunable low-noise amplifier and a multi-frequency tuning implementation method therefor. The amplifier comprises: a system controller (13) and a micro-electro-mechanical system (MEMS) matching tuner (12) connected to the system controller (13). The system controller (13) is configured to respond to a first operation executed by a user via a user interface (15) when in a first mode, to acquire a first matching value produced on the basis of the first operation, and to output the first matching value to the MEMS matching tuner (12). The MEMS matching tuner (12) is configured to be controlled by the system controller (13) and to support the amplifier working on different frequency bands in tuning processing, thus allowing the matching value of the MEMS matching tuner (12) itself to match a current working frequency band. |
