| Popis: | This paper presents the design approach and test results of a four-stage 1.6-W K-band MMIC power amplifier developed for point-to-point radio applications. The design of the power amplifier was based on a small signal low loss matching technique. The MMIC was fabricated employing GaAs based high-performance 0.4 μm multifunction self-aligned gate MESFET technology. We achieved a minimum PAE of 22%, output power of 1.6 W (0.53 W/mm power density) and associate gain of 18 dB over the 17.5–20 GHz frequency range. Thus, we successfully applied a small signal technique in a four-stage K-band MMIC power amplifier to achieve bandwidth, power output and PAE performance objectives. © 2007 Wiley Periodicals, Inc.
