Abstract:
Described embodiments provide a transmission-line resistance compression network that includes an input port, a first output port coupled to a first load and a second output port coupled to a second load. The first and second loads may have substantially similar input impedances under substantially similar operating conditions. The transmission-line resistance compression network includes a transmission-line network coupled to the input port, the first output port and the second output port, and includes at least two transmission lines of different lengths. For a first operating range, the resistances at input ports of the first and second loads vary over first and second ratios, respectively. The resistance of the input impedance at the input port of the transmission-line resistance compression network varies over a third ratio that is smaller than at least one of the first and second ratios.
