Abstract
A variable impedance device includes a passive tuner that includes at least one variable component, which is controllable to apply a variable impedance value to an input signal of the passive tuner. A low noise amplifier is configured to supply the input signal to the passive tuner by amplifying an input RF (radio frequency) signal.
