The investigation results of the possibility of manufacturing radiation tolerant microwave amplifiers implementing in domestic GaAs D-mode pHEMT 0.5 μm process are presented in this work. The amplifier with an operating frequency range from 0.1 GHz to 3.5 GHz, gain above 15 dB, noise figure below 2.2 dB, output linearity above 17 dBm is designed, produced and measured. The characteristic property of the amplifier is a single positive supply voltage and extended frequency range up to 100 MHz provided by the external capacitor circuit. Transient radiation effects in the amplifier are investigated up to the dose rate value of 4.9·109 a.u./s. The recovery time does not exceed 4 μs according to the experimental results.
