摘要
A mobile device comprising an antenna, a receiver coupled to the antenna, and a transmitter coupled to the antenna, wherein the receiver, the transmitter, or both comprise a low noise amplifier comprising an adjustable gain and a variable impedance controller, and wherein the low noise amplifier is configured to sink current and to adjust a shunt resistance substantially simultaneously. Included is a method comprising receiving an electrical signal, substantially simultaneously adjusting an input impedance and a gain factor, amplifying the electrical signal, thereby producing an amplified signal, and outputting the amplified signal.
