Abstract
The present invention is directed to an impedance matching network for use at a predetermined frequency. The network includes: a low impedance port having a first impedance substantially equal to an impedance of an RF amplifier port; a first distributive transmission line network coupled to the low impedance port, the first distributive transmission line network including a plurality of first transmission lines, each first transmission line being characterized by a first characteristic impedance and a first electric line length at the predetermined frequency to form a first quasi-lumped reactive element so that the plurality of first transmission lines form a first quasi-lumped element impedance matching stage; at least one second distributive transmission line network coupled to the first distributive transmission line network and a high impedance port, the second distributive transmission line network including a plurality of second transmission lines, each second transmission line being characterized by a second characteristic impedance and a second electric line length at the predetermined frequency to form a second quasi-lumped reactive element so that the plurality of second …
