摘要： A power combiner which maintains substantially constant power combining efficiency with variable output power includes a set of unit amplifiers that are coupled by the power combiner. The power combiner includes a first plurality of a quarter wavelength transmission line sections coupled to the output of each unit amplifier. The second end of each one of the first plurality of quarter wavelength transmission line sections are successively coupled by a corresponding second plurality of quarter wavelength transmission line sections, with the succeeding or last one of said unit amplifiers having its quarter wavelength transmission line section coupled to an output terminal. The power combiner permits unit amplifiers in the amplifier module to be switched off in succession as less output power is required while maintaining substantially constant power combining efficiency, and hence substantially constant D.C. to r.f. conversion efficiency.

Each one of the FETS has a plurality of cell portions, each cell portion having drain, gate and source regions, the source and drain regions of the cell portions being connected in parallel. A first selected portion of the gate regions of each one of said FETS is connected to a gate electrode. A second selected remaining portion of the gate regions of each one of the FETS has the gate regions thereof physically isolated from the gate electrode. A signal fed to the gate electrode of each FET is distributed to the connected gate regions of each field effect transistor. In response to such signal, the total drain-source resistance of such FET is changed between a predetermined low value and a predetermined high value, with the resistance of the predetermined high value being determined, in part, by the number of such isolated gate regions.
