Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A variable impedance device comprising: an RF input node; an RF output node; a passive tuner comprising a variable resistor and a variable capacitor, wherein the variable resistor and the variable capacitor are coupled in series between the RF input node and the RF output node and wherein the passive tuner is controllable to apply a variable impedance value to an input signal of the passive tuner at the RF input node; and a low noise amplifier coupled…
