Zusammenfassung:	Provided are an input impedance matching network and a RF front-end module. The input impedance matching network comprises a first pad, a second pad, and a first inductor with one end connected to the first pad and another end connected to the second pad; an output end of the second pad, as an output end of the input impedance matching network, is configured to be connected to an input end of a low noise amplifier; the input impedance matching network further comprises a compensation regulation circuit connected with the first pad and/or the second pad, and the compensation regulation circuit is configured to regulate a parasitic capacitance of the first pad to the ground and/or a parasitic capacitance of the second pad to the ground, so that the parasitic capacitance of the first pad to the ground is greater than that of the second pad to the ground.
