2025 June-1 - 214 articles

Cover Story: A robust three-stage 13–15 GHz low-noise amplifier (LNA) using pHEMT GaAs technology is presented, achieving simultaneous signal and noise matching (SSNM). The proposed design demonstrates a 25 dB gain and a noise figure below 1.6 dB across the band, validated by measurements. Its performance under high-power pulsed and continuous signals is assessed, showing resilience and stability. This work offers practical insights into interstage matching and reliable LNA design for space applications. View this paper
