PURPOSE: A logic low noise amplifier and its amplification control method are provided, which have constant performance as to an RF signal having wider electric field intensity. CONSTITUTION: According to the low noise amplifier used in an RF receiver including an antenna and an input synchronizer and an amplifier and a detector, an RF amplification control circuit part(110) controls amplification of an RF signal according to the electric field intensity of the received RF signal. A low noise amplification circuit part(120) amplifies the RF signal by the control of the RF amplification control circuit part. And a pass circuit part(130) passes the RF signal by the control of the RF amplification control circuit part.
