Abstract
A low dc power RTD microwave amplifier utilizing a hybrid-coupled reflection-type topology is presented. The low-power microwave amplifier, which consists of a quadrature hybrid coupler and two RTDs, is implemented using an InP-based MMIC technology. The fabricated RTD amplifier shows low dc power consumption of 470 W with high gain of 11.5 dB at 5 GHz, resulting in high FOM of 24.5 dB/mW. The amplifier IC is the first demonstration of a low-power microwave amplifier based on the RTD device technology.
