<P>PROBLEM TO BE SOLVED: To improve a low noise amplification circuit in a tuner. Ž<P>SOLUTION: The present disclosure relates to a low noise amplification circuit in a tuner. This circuit includes: a high frequency (RF) amplification transistor (TR) (Q1) mounted between a signal input terminal and a signal output terminal; an internal voltage input terminal for applying an internal voltage input as a bias voltage to the high frequency amplification transistor (Q1); and a port for controlling biasing of the high frequency amplification transistor (Q1) by switching the bias voltage applied from the internal voltage input terminal to the high frequency amplification transistor (Q1).
