Abstract
A low noise amplifier circuit includes a first low noise amplifier including a common gate structure cascoded with a parallel common source structure to selectively amplify a band signal among first and second band signals; a second low noise amplifier including a common gate structure cascoded with a parallel common source structure to selectively amplify a band signal among third and fourth band signals; an output DPDT circuit including a first input terminal connected to the first low noise amplifier, a second input terminal connected to the second low noise amplifier, and a first output terminal and a second output terminal for selectively outputting signals input through the first input terminal and the second input terminal; and a control circuit performing an amplification control and a switching control for the first and second low noise amplifiers and the output DPDT circuit in response to a predetermined communications scheme.
