Abstract :
An X-band monolithic-microwave integrated-circuit (MMIC) power amplifier with a simplified on-chip temperature-compensation circuit composed of a few diodes and a resistor are presented in this paper. At first, the operation principle and design method of the temperature-compensation circuit have been investigated. The fabricated four-stage X-band MMIC power amplifier with the on-chip temperature-compensation circuit has demonstrated the improvement of gain variation from 5.5 to 1.3 dB in the temperature range from -10°C to +80°C
