Abstract
A broadband low noise amplifier and amplification method is provided. The broadband low noise amplifier includes an input terminal into which a radio frequency (RF) signal received by an antenna is input, an output terminal from which an amplified RF signal is output, at least one gain control part connected in parallel with loads of the output terminal to adjust the gain of the amplified RF signal, and at least one load tuning part that resonates with loads of the output terminal to adjust the resonance frequency of the load impedance. The method includes amplifying the input RF signal and outputting the amplified RF signal to an output terminal, where a gain of the amplified RF signal is adjusted by switching operations of at least one switching device connected in parallel with a load of the output terminal.
