In this paper, we report a computational autonomous design of a 24 GHz one-stage microwave amplifier, which is a key device for high-speed communication. A novel fitness function for particle swarm optimization (PSO) is introduced and a microwave amplifier is optimized by considering stability, center frequency, gain, and bandwidth. Moreover, we consider the parameters of PSO such as inertia coefficient, the number of particles, and topology to ensure immunity against a local optimum and accelerate the convergence. As a result, a 12 mW, 24 GHz amplifier, which has 10.8 dB gain and 3.8 GHz bandwidth, is designed autonomously in an hour.
