Abstract: Conventional broadband RF power amplifiers use a ¼ wavelength transmission line to decouple the gate bias DC source from the gate circuitry and a second ¼ wavelength transmission line to decouple the drain bias DC source from the drain circuitry, taking up considerable printed circuit board space. A novel broadband RF power amplifier uses a transistor with separate terminals for injection of gate bias and drain bias DC sources, eliminating the need for ¼ wavelength transmission lines, thereby freeing up space and allowing higher density packaging. The power amplifier transistor can be implemented with a single die circuit or multiple die circuits operating in parallel.
