The invention provides a front end of a wireless communication transceiver. The front end of the wireless communication transceiver comprises a transceiving switch, a low-noise amplifier and a power amplifier. The transceiving switch comprises a control end, an antenna interface end, a first transceiving end and a second transceiving end, wherein the antenna interface end is electrically connected with an antenna, the first transceiving end is electrically connected with the low-noise amplifier, the second transceiving end is electrically connected with the power amplifier, the control end is used for controlling the antenna interface end to be conducted with the low-noise amplifier through the first transceiving end or to be conducted with the power amplifier through the second transceiving end, the low-noise amplifier and the power amplifier are both of multistage amplifying structures, and multi-order broadband matching networks comprising a plurality of pi-type networks and LC networks are arranged between the antenna interface end and the input end of the low-noise amplifier as well as between the antenna interface end and the output end of the power amplifier. With the adoption of the front end of the wireless communication transceiver, the insertion loss of the transceiving switch in the whole bandwidth is effectively reduced.
