Abstract

The distributed amplifier approach allows the output powers of several FETs to be combined without the need for multi-way power combiners. In this paper we demonstrate that a balanced amplifier employing two single-ended dual-fed distributed amplifiers can operate effectively under class-B operation. Class-B operation and dual-feeding allow distributed amplification with significantly improved efficiencies compared to conventional distributed power amplifiers. The FETs are spaced 180 degrees to allow all FETs operate into identical optimum loadlines. The configuration uses all FET output power and has good port match.
