摘要

The successful development of a new four-stage 1-W AlGaAs/InGaAs/GaAs PHEMT MMIC with a temperature-compensating GaAs feedback resistor is reported. It was found that we can signifi cantly reduce the gain variation in the temperature range between -40 and 80°C from 7 dB to less than 3 dB by using the temperature-compensating GaAs feedback resistor. It was also found that the use of the GaAs feedback resistor will neither result in a decrease in output power nor a decrease in the PAE of Psat for the temperature compensated power amplifier.
