1. A low noise amplifier comprising:
an input configured to receive a radio frequency receive signal;
a first amplification stage including a first gain transistor having a gate connected to the input, a second gain transistor having a gate connected to the input and a source connected to a source of the first gain transistor, a first selection transistor having a source connected to a drain of the first gain transistor, and a second selection transistor having a source connected to a drain of the second gain transistor; and
a second amplification stage having a lower gain than the first amplification stage, the low noise amplifier operable in a first gain mode in which the first amplification stage and the second amplification stage operate in a cascade to amplify the radio frequency receive signal, and a second gain mode in which the first amplification stage amplifies the radio frequency receive signal and the second amplification stage is bypassed.
